The following deadlock in the usb subsystem can be triggered during kdump:
systemd-udevd[402]: usb3: Worker [419] processing SEQNUM=2194 is taking a long time
dracut-initqueue[432]: Timed out while waiting for udev queue to empty.
systemd-udevd[402]: usb3: Worker [419] processing SEQNUM=2194 killed
systemd-udevd[402]: usb3: Worker [419] terminated by signal 9 (KILL).
...
kdump[720]: saving vmcore complete
...
systemd-shutdown[1]: Rebooting.

During crashkernel's boot, hub_event() takes usb_lock_device(hdev) of the
root hub and keeps it for the whole hub processing loop, since it calls
hub_port_connect() -> usb_alloc_dev() -> xhci_alloc_dev(). If during kdump
another device (e.g., a mis-initialized dGPU) hogs interrupts or DMAs, the
TRB_ENABLE_SLOT command will be blocked from completion in time, moving
the HC to an unstable condition (e.g., HSE in USBSTS). After vmcore gets
captured, init calls device_shutdown() trying to shut down the hub device,
by also trying to take the same lock still held by the hub kworker task.
Avoid the deadlock by adding a 2x timeout for command completion before
calling xhci_hc_died(). This gives enough time before marking the host un-
stable, dying and calling xhci_cleanup_command_queue(); which unblocks the
hub worker into releasing the lock, allowing device_shutdown() to proceed.

What specifically have you seen? If you have actually observed HSE (how?), maybe xhci-hcd could detect it automatically by the same means and clean up immediately. > After vmcore gets captured, init calls device_shutdown() trying to > shut down the hub device, by also trying to take the same lock still > held by the hub kworker task. > > Avoid the deadlock by adding a 2x timeout for command completion nit: not a deadlock if X waits for Y and Y is just stuck by itself. > before calling xhci_hc_died().

Many functions which wait for command completion without timeouts. Patch this one and you will get stuck in the next. This shouldn't be happening in the first place. If a command doesn't complete normally in time then xhci_handle_command_timeout() should abort it, and if that times out too, then hc_died(). So not sure why this hasn't happened here. Is it reproducible? Can you try again with debug logs? echo 'module xhci_hcd +p' >/proc/dynamic_debug/control Regards, Michal ^ permalink raw reply [flat|nested] 25+ messages in thread

Right after xe and drm set the dGPU (Battlemage G31) during the boot of the crashkernel, I see the `usb worker taking a long time` messages. Afterwards, kdump is able to capture a vmcore completely, the systems tries to reboot and hangs with the xhci_alloc_dev() and device_shutdown() stack traces I provided. > If you have actually observed HSE (how?), maybe xhci-hcd could detect > it automatically by the same means and clean up immediately. That's exactly what I was expecting xhci-hcd to do when I first started looking at this bug, however it does not detect it automatically. As for how I saw HSE, while testing the patch before submission, since I already had the xhci lock, I just added a read of the usbsts before calling xhci_hc_died(xhci): ... - wait_for_completion(command->completion); - slot_id = command->slot_id; + if (!wait_for_completion_timeout(command->completion, + msecs_to_jiffies(2 * command->timeout_ms))) { + spin_lock_irqsave(&xhci->lock, tflags); + usbsts = readl(&xhci->op_regs->status); + xhci_err(xhci, + "TRB_ENABLE_SLOT: no command completion after %lums, USBSTS:%s\n", + 2 * command->timeout_ms, + xhci_decode_usbsts(ststr, usbsts)); + xhci_hc_died(xhci); + spin_unlock_irqrestore(&xhci->lock, tflags); + } ... This debug version of the patch printed: [ 17.481330] xhci_hcd 0000:80:14.0: TRB_ENABLE_SLOT: no command completion after 10000ms, USBSTS: 0x00000015 HCHalted HSE PCD In the end, I didn't add the read of usbsts in the version I submitted because not only xhci_hc_died(xhci) prints errors messages, but now since slot_id is NULL, the next error messages will be printed; before xhci_alloc_dev() safely returns 0 and the system reboots smootly.

To come up with this timeout logic, I actually "borrowed" the idea from the original commit described on Fixes c311e391a7efd ("xhci: rework command timeout and cancellation,") In the past, before the wait_for_completion rearrangement done in that commit, this part of xhci_alloc_dev() code used to have calls to wait_for_completion_interruptible_timeout() waiting for XHCI_CMD_DEFAULT_TIMEOUT. Furthermore, just to give another chance I added a bit more time by putting `2 * command->timeout_ms` in the patch. However, I have tested with XHCI_CMD_DEFAULT_TIMEOUT=5000ms and this also works. If XHCI_CMD_DEFAULT_TIMEOUT it thought to be better, if this patch gets approved, I can send a v2 with XHCI_CMD_DEFAULT_TIMEOUT instead of 2x that. > So not sure why this hasn't happened here. > Is it reproducible?

Always reproduceable - just need to issue `echo c > /proc/sysrq-trigger` on the system. > echo 'module xhci_hcd +p' >/proc/dynamic_debug/control Actually, from the beginning of all my debugging I already had `usbcore.dyndbg=+p xhci_hcd.dyndbg=+p xhci_pci.dyndbg=+p` on the kernel cmdline, as well as on the crashkernel's KDUMP_COMMANDLINE_APPEND at /etc/sysconfig/kdump.

Hmm, the "Command timeout on stopped ring" case doesn't obviously lead to any immediate command completion, and ringing the command doorbell under HSE won't achieve any progress. Maybe that's the bug. Could you post full crash kernel dmesg up to that point? Not sure how it got to this place. When xhci_handle_command_timeout() logs USBSTS, does it help to add: if (usbsts & STS_FATAL) { xhci_halt(xhci); xhci_hc_died(xhci); goto time_out_completed; } It may not be perfect solution (race conditions?) but it could hint that we are on the right track, if it works.

Any chance it's not a problem with my proposed change but some sort of issue on your side? Anyway, I think the patch below might cover it. It works for me in the sense that the bus does get killed, without ill effect. I tested on VL805 where HSE is easily triggered by disabling XHCI_TRB_OVERFETCH. However, the patch isn't necessary here - VL805 doesn't clear CRCR.CRR on HSE, so normal abort path is taken and times out, then hc_died(). Can somebody serious confirm if this issue actually exists in the first place, and whether the patch solves it? Hello Redhat, anyone alive there? Or only stochastic parrots? Mathias, do you remember what's the point of the "Command timeout on stopped ring" branch? Can it happen in any case other than dead chip? I also wonder if it wouldn't make sense to just hc_died() on every command timeout except Address Device. We rely on Stop Endpoint timeouts to kill chips which go unresponsive without setting HCE/HSE, because sooner or later somebody loses patience and unlinks an URB, but this story (real or hallucinated, but plausible) shows that this may not help when there are no devices created yet. --- diff --git a/drivers/usb/host/xhci-ring.c b/drivers/usb/host/xhci-ring.c index e5823650850a..3041deb67b57 100644 --- a/drivers/usb/host/xhci-ring.c +++ b/drivers/usb/host/xhci-ring.c @@ -1761,13 +1761,15 @@ void xhci_handle_command_timeout(struct work_struct *work) /* mark this command to be cancelled */ xhci->current_cmd->status = COMP_COMMAND_ABORTED; - /* Make sure command ring is running before aborting it */ + /* check for crashed or disconnected chip */ hw_ring_state = xhci_read_64(xhci, &xhci->op_regs->cmd_ring); - if (hw_ring_state == ~(u64)0) { + if (hw_ring_state == ~(u64)0 || usbsts & (STS_FATAL | STS_HCE)) { + xhci_info(xhci, "kill the damn thing\n"); xhci_hc_died(xhci); goto time_out_completed; } + /* Make sure command ring is running before aborting it */ if ((xhci->cmd_ring_state & CMD_RING_STATE_RUNNING) && (hw_ring_state & CMD_RING_RUNNING)) { /* Prevent new doorbell, and start command abort */ ^ permalink raw reply related [flat|nested] 25+ messages in thread

Don't think so, since I'm using the same system and procedures I used for the wait_for_completion_timeout() patch: https://lore.kernel.org/linux-usb/20260430014817.2006885-1-desnesn@redhat.com/T/#ma6ce987cea510349082831bbb822136e5c5c57da > Anyway, I think the patch below might cover it.

Now I'm just confused. No, guess you actually saw a case of poor explanation on my end - apologies for not explaining the outcome properly. What I tried poorly to explain was that the system simply hanged after I intentionally triggered the panic with a sysrq - both times. Nothing happens after the sysrq panic stack trace. > > Kdump doesn't run and no vmcore is produced: > Is the kdump kernel not launched, or does it crash during boot? > The latter would make sense if there is some problem with the code.

Both kernels booted normally: the first one checking HSE after USBSTS was logged on xhci_handle_command_timeout(), as well as this new code checking for ring state or the HSE and HCE bits.

Well, that's weird.

It could show on the main kernel before the panic is triggered, if the main kernel was patched too. Maybe they are the same kernel binary? I'm trying to come up with any conceivable theory how patching xhci-hcd could prevent the kdump kernel from loading. Still no idea...

Just found the reason: with the installation of this last kernel, my /boot partition got filled. Thus, the initframs image was not actually getting copied to /boot. After removing a few test kernels, kdump armed normally, collected a vmcore and no hangs due to the locks of xhci_alloc_dev() or device_shutdown() appeared.

That's not a great news because it seems that the same HSE could occur on any kexec, not just kdump. It's unclear why it happens, it seems that after initial boot the HC works normally (does it?) but then kexec-ing breaks it somehow. I don't think this has anything to do with the Battlemage, because in the particular case which you shared, GPU began initialization *after* HSE had already been logged. My first wild guess would be that HSE is caused by resetting IOMMU while the xHC is unaware of kexec and continuing to DMA old buffers. Attached patch checks for this and also tries to explicitly clear HSE, although resetting ought to clear it too. But HW has bugs... So it may not help, but maybe it will if we are lucky, or at least it may offer some hint about when things go wrong. > So, I confirm that this patch, which checks for HSE or HCE indeed > fixes the bug, without having to rely to a > wait_for_completion_timeout(): > > # grep -i HSE -A5 kexec-dmesg.log > [Sun May 3 11:37:36 2026] xhci_hcd 0000:80:14.0: Command timeout, > USBSTS: 0x00000015 HCHalted HSE PCD > [Sun May 3 11:37:36 2026] xhci_hcd 0000:80:14.0: kill the damn thing > [Sun May 3 11:37:36 2026] xhci_hcd 0000:80:14.0: xHCI host controller > not responding, assume dead > [Sun May 3 11:37:36 2026] xhci_hcd 0000:80:14.0: HC died; cleaning up > [Sun May 3 11:37:36 2026] xhci_hcd 0000:80:14.0: Error while > assigning device slot ID: Command Aborted Thanks for testing, that's what the patch was intended to do.

Hi again, I see a certain lack of interest in finding the root cause of this. I have done a simple test on my own HW: writing bogus CRCR to cause IOMMU fault when the first command is submitted. I found that not all HCs reliably set HSE in this case, but obviously none of them ever complete the command properly. It seems that unconditional hc_died() on Enable Slot timeout may not be a bad idea. Makes me wonder if the same shouldn't apply to all commands besides Address Device, they typically only timeout due to HW issues.

I've just read HSE at these places and confirmed that HSE was already set even before queuing the enable slot trb, even though it was previously clear in xhci_gen_setup().

I guess I would had expected to have HSE always being set in these kind of situations in the command ring register. Just out of curiosity, how did you figure out that only some HCs set HSE? Tested on a few HCs or inferred that somehow? > It seems that unconditional hc_died() on Enable Slot timeout may not be a bad idea. That was the idea of the original patch when I saw the HSE at that point of the reboot sequence after the vmcore was captured. However, different from my original patch, only one XHCI_CMD_DEFAULT_TIMEOUT is enough (even tested a few weeks ago after submission). Now if we can't trust that all HCs will reliably set HSE on scenarios like this one (iommu issues on the crashkernel?), the unconditional hc_died() starts to feel like a safer approach. > Makes me wonder if the same shouldn't apply to all commands > besides Address Device, they typically only timeout due to HW issues.

Attached xhci debugfs patch adds a list of almost all memory the xHC is allowed to access, including (if I havevn't missed something) all mappings it is allowed to access before any slots are enabled. Please apply, reboot and then: zip -r before.zip /sys/kernel/debug/usb/xhci/0000:80:14.0 # trigger crash kexec and the bug zip -r after.zip /sys/kernel/debug/usb/xhci/0000:80:14.0 Note: if you need to use tar instead, copy the directory and then archive the copy, because tar doesn't work on debugfs directly. And since the bug may be an out of bounds access by the HW, if you don't mind running slightly experimental patch to a critical subsystem, please also apply the DMA guard pages patch. I've been using it for a few months without issues, but YMMV. It helps determine which mapping is accessed OOB. Note: DMA guard pages may casue USB to stop working before kexec if it's a HW bug masked by memory layout, or begin to work after kexec in case of some IOMMU subsystem issues. > PS: there was a big iommu PR a few days ago - all the results from on > this email were performed with a recent 7.1.0-rc3 kernel checked out > at 30e0ff6d6a83. Well, so those IOMMU changes neither broke it nor fixed it. Knowing xHCI I frankly suspect that the problem is here.

Sorry, I forgot about the most important thing: crash kernel log, or at least the IOMMU fault message showing the bad address. However, in this case it's moot because it seems that the HC didn't fault after kexec and it worked normally - debugfs shows that USBSTS=0 and some device has been successfully enabled. (It's a little odd that CRCR.CRR appears to be clear, not sure what's the deal with that, but it's same thing in before.zip as well.) So either the bug isn't as deterministic as we thought, or one of the patches "fixed" it, and that could only be DMA Guard Pages. If you can't reproduce the problem with guard pages, please remove that patch and post before/after debugfs again, plus crash kernel dmesg.

I was indeed intrigued and almost sent it without you asking for it :-) The crashkernel's fault address is shown latter on down below, but now I have attached the full kexec dmesg too. PS: Note that the debugfs file 'memory' from before contains the addresses of the main kernel, not crashkernel's addresses: - From main dmesg: [ 6.728105] xhci_hcd 0000:80:14.0: Device context base array address = 0x000000010a958000 (DMA), 00000000f542e3ba (virt) [ 6.737602] xhci_hcd 0000:80:14.0: ERST deq = 64'h10a95a000 > However, in this case it's moot because it seems that the HC didn't > fault after kexec and it worked normally - debugfs shows that USBSTS=0 > and some device has been successfully enabled.

And it doesn't look like the guard pages patch is working here. But maybe it doesn't matter. Your "memory" files show a clear pattern of consecutive page-sized allocations (example from after.zip): 102fb6000 DCBAA 102fb7000 CR 102fb8000 ER segmnet 0 102fb9000 ER segment 1 102fba000 ERST We can make a guess that the faulting address is the ERST, which definitely should be accessible to the host controller. This simple patch logs ERST allocation and freeing; as far as I see nothing else touches that mapping. If the ERST is somehow freed before starting the HC, that's a bug.

Recap: After I triggered the panic, the system collects a vmcore smootly, but does not reboot afterwards. The crashkernel was not completing a TRB_ENABLE_SLOT command in xhci_alloc_dev() in xhci.c, which made xhci hold the xhci->lock and block a systemd kworker that was also waiting for that lock on device_shutdown(). Basing myself on past code, I created a first patch that aborted the TRB_ENABLE_SLOT command with wait_for_completion_timeout() and killed the HC - this released the lock and enabled the kworker to finish. However, after a few messages and test patches with Michal, we weren't totaly sure if this was good solution, mostly because we noticed that HSE was already set way before ever reaching that TRB_ENABLE_SLOT command. Iommu: At that moment, I noticed that dmar faults were happening to the e1000e and xhci drivers that shared the same bus. Michal noticed that the faulting address was a successful dma_alloc_coherent() allocation in xhci_alloc_erst(). This stated to point to an IOMMU bug. Afterwards, I tested booting the crashkernel with `intel_iommu=off` and confirmed that it rebooted smootly after vmcore was captured, so the plot tickened even more for an iommu bug. Diging deaper, I started to suspect that the copy of bus 128's root entry was being changed to have the Present bit cleared somehow. This made me write a v2 patch for the bug, now in iommu, which instead of copying the root-entry table, it disabled translation and allocated a clean root-entry table immediately if running a kdump kernel: no DMAR faults and smooth reboot was caried out. Following this lead, I patched the code to dump the root entries table using DMAR_RTADDR_REG before calling iommu_alloc_root_entry() (in init_dmars() at drivers/iommu/intel/iommu.c), while also observing bus 0x80's root entry right at the end of copy_translation_tables(): [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: root[ 0]: lo=0x000000018a67f001 (P=1 LCTP=0x000000018a67f000) hi=0x00000001f855d001 (P=1 UCTP=0x00000001f855d000) [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: root[ 1]: lo=0x00000001f8562001 (P=1 LCTP=0x00000001f8562000) hi=0x0000000000000000 (P=0 UCTP=0x0000000000000000) [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: root[ 2]: lo=0x00000001f8564001 (P=1 LCTP=0x00000001f8564000) hi=0x0000000000000000 (P=0 UCTP=0x0000000000000000) [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: root[ 3]: lo=0x00000001f8566001 (P=1 LCTP=0x00000001f8566000) hi=0x0000000000000000 (P=0 UCTP=0x0000000000000000) [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: root[ 4]: lo=0x00000001f8569001 (P=1 LCTP=0x00000001f8569000) hi=0x0000000000000000 (P=0 UCTP=0x0000000000000000) [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: root[ 5]: lo=0x00000001f856b001 (P=1 LCTP=0x00000001f856b000) hi=0x0000000000000000 (P=0 UCTP=0x0000000000000000) => [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: root[128]: lo=0x0000000000000000 (P=0 LCTP=0x0000000000000000) hi=0x00000001f856d001 (P=1 UCTP=0x00000001f856d000) [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: root[129]: lo=0x00000001f8583001 (P=1 LCTP=0x00000001f8583000) hi=0x0000000000000000 (P=0 UCTP=0x0000000000000000) [Wed Jun 3 15:40:37 2026] DMAR: dmar1: debug: 8 of 256 root entries non-zero [Wed Jun 3 15:40:37 2026] DMAR: Translation already enabled - trying to copy translation structures => [Wed Jun 3 15:40:37 2026] DMAR: dmar1: post-copy root[128]: lo=0xe89cda001 hi=0x0 [Wed Jun 3 15:40:37 2026] DMAR: Copied translation tables from previous kernel for dma ...

On bus 0x80, I have e1000e at 80:1f.6 (devfn 0xfe) and xHCI at 80:14.0 (devfn 0xa0), so the hardware root entry correctly has lo=0 and hi=UCTP present. However, after copy_translation_tables(), I noticed that root[128].hi was zeroed-out (Present bit cleared) and another (expected) different value on root[128].lo. In short, the culprit here is having a zeroed LCTP, since at copy_context_table() the allocation of new_ce for LCTP context entries currently governs the pos variable; which is later used to save new_ce entries for UCTP at tbl[tbl + pos]. On the first iteration idx will be zero, old_ce_phys will be empty, thus this moves the loop straight to devfn=0x80. At devfn 0x80, idx wraps to 0 again ( (devfn * 2) mod 256), but since no new_ce was previouly allocated for LCTP context entries, pos will remain zero while copying UCTP context entries. After all upper context entries are saved, tbl will receive new_ce from UCTP at tbl[tbl_idx + 0], and not tbl[tbl_idx + 1]. These will be later written in copy_translation_tables() to iommu->root_entry[bus].lo and iommu->root_entry[bus].hi, which causes the bug. In summary, the hardware tables were correct, but the copy path misplaced the UCTP table for bus 0x80 when dealing with a LCTP zeroed-out during kdump. To fix this, I created a v3 patch that uses devfn to better track which half we are copying, so UCTP-only buses (lo=0, hi=P) are installed into the upper root half. I am doing some final tests now, but since this was a lot to digest, comments at this stage will be most appreciated. To IOMMU maintainers: should I send this patch to the iommu mailing list and move the discussion there? Thanks in advance for any help on the matter, Best Regards, Desnes [-- Attachment #2: 0001-iommu-vt-d-Fix-UCTP-context-table-slot-when-copying-.rfc.patch --] [-- Type: text/x-patch, Size: 2912 bytes --] From 4b283de2c156e270d16e292acb10884f42c0bd12 Mon Sep 17 00:00:00 2001 From: Desnes Nunes <desnesn@redhat.com> Date: Tue, 9 Jun 2026 23:57:05 -0300 Subject: [PATCH RFC] iommu/vt-d: Fix UCTP context table slot when copying root entries 'Content-type: text/plain' When translation is already enabled at boot (e.g. kdump), the vt-d driver copies context tables from the previous kernel's root table. In scalable mode, buses that only populate the upper root half (UCTP, devfn >= 0x80) should be written to ctxt_tbls[tbl_idx + 1] through copy_context_table(). However, the current copy path always uses tbl[tbl_idx + 0] in this situa- tion. Since idx wraps to 0 at devfn 0x80 due to a zeroed LCTP, new_ce for LCTP will be NULL and keep pos equals to 0. Thus, UCTP entries will be co- pied into tbl[tbl_idx + 0] instead of tbl[tbl_idx + 1], and written after- wards to root_entry[bus].lo instead of .hi in copy_translation_tables(). As consequence, devices on bus 0x80 with devfn >= 0x80 fail DMA with fault 0x39, which breaks drivers running in kernels with translation pre-enabled. This fixes NO_PASID DMAR faults for UCTP-only buses such as: DMAR: [DMA Read NO_PASID] Request device [80:14.0] fault addr 0xe81759000 [fault reason 0x39] SM: Present bit in Root Entry is clear Fixes: 091d42e43d21 ("iommu/vt-d: Copy translation tables from old kernel") Signed-off-by: Desnes Nunes <desnesn@redhat.com> --- drivers/iommu/intel/iommu.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/drivers/iommu/intel/iommu.c b/drivers/iommu/intel/iommu.c index 4d0e65bc131d..737936f942a0 100644 --- a/drivers/iommu/intel/iommu.c +++ b/drivers/iommu/intel/iommu.c @@ -1443,7 +1443,7 @@ static int copy_context_table(struct intel_iommu *iommu, struct context_entry **tbl, int bus, bool ext) { - int tbl_idx, pos = 0, idx, devfn, ret = 0, did; + int tbl_idx, tbl_slot = 0, idx, devfn, ret = 0, did; struct context_entry *new_ce = NULL, ce; struct context_entry *old_ce = NULL; struct root_entry re; @@ -1459,10 +1459,9 @@ static int copy_context_table(struct intel_iommu *iommu, if (idx == 0) { /* First save what we may have and clean up */ if (new_ce) { - tbl[tbl_idx] = new_ce; + tbl[tbl_idx + tbl_slot] = new_ce; __iommu_flush_cache(iommu, new_ce, VTD_PAGE_SIZE); - pos = 1; } if (old_ce) @@ -1484,6 +1483,9 @@ static int copy_context_table(struct intel_iommu *iommu, } } + /* Track if saving UCTP or LCTP entries in scalable mode */ + tbl_slot = ext && devfn >= 0x80 ? 1 : 0; + ret = -ENOMEM; old_ce = memremap(old_ce_phys, PAGE_SIZE, MEMREMAP_WB); @@ -1512,7 +1514,7 @@ static int copy_context_table(struct intel_iommu *iommu, new_ce[idx] = ce; } - tbl[tbl_idx + pos] = new_ce; + tbl[tbl_idx + tbl_slot] = new_ce; __iommu_flush_cache(iommu, new_ce, VTD_PAGE_SIZE); -- 2.54.0 ^ permalink raw reply related [flat|nested] 25+ messages in thread

Looks like no one from IOMMU pays much attention in the first place. Let's see if a subject change helps.
