Hi Mario

Nick Hastings reported in Debian in https://bugs.debian.org/1036530
lockups from his system after updating from a 6.0 based version to
6.1.y.

#regzbot ^introduced 24867516f06d

Does this ring some bell for you? Do you need any further information
from Nick?

Hi Salvatore,

Have Nick try using "pcie_port_pm=off" and see if it helps the issue.

Does this happen in the latest 6.4 RC as well?

I think we need to see a full dmesg and acpidump to better characterize it.

I booted into a 6.1 kernel with this option. It has been running without
problems for 1.5 hours. Usually I would expect the lockup to have
occurred by now.

> Does this happen in the latest 6.4 RC as well?

I have compiled that kernel and will boot into it after running this one
with the pcie_port_pm=off for another hour or so.

Please find attached. Let me know if there is anything else I can provide.

Nick.

I don't see nouveau loading, are you explicitly preventing it from 
loading?  Can I see the journal from a boot when it reproduced?

I let this run for 3 hours without issue.

I'm now running 6.4.0-rc4 without seeing the problem after 1 hour.

I did however see two unrelated problems that I include here for
completeness:
1. iwlwifi module did not automatically load
2. Xwayland used huge amount of CPU even though was not running any X
programs. Recompiling my wayland compositor without XWayland support
"fixed" this.

Yes nouveau is blacklisted.

Hmm not sure which n for "journalctl -b n" maps to which kernel (is that
what you are requesting?). The commit hash doesn't not seem to be
listed. I may have to boot into a bad kernel again.

I did eventually see a lockup of this kernel. On the console I saw:

[  151.035036] vfio-pci 0000:01:00.0 Unable to change power state from D3cold to D0, device inaccessible

I did not see the other two lines that were present in earlier lock ups

Please find attached the output from a "journalctl --system -bN" for a
kernel that has this issue.

In this log I see nouveau loaded, but I also don't see the failure 
occurring.

As you're actually loading nouveau, can you please try nouveau.runpm=0 
on the kernel command line?

If that helps the issue; I strongly suggest you cross reference the 
latest kernel to see if this bug still exists.

I never saw anything in the logs from a lockup either. I had assumed it
was no longer able to write to disk. The failure did occur on that
occasion.

I'm not intentionally loading it. This machine also has intel graphics
which is what I prefer. Checking my
/etc/modprobe.d/blacklist-nvidia-nouveau.conf
I see:

blacklist nvidia
blacklist nvidia-drm
blacklist nvidia-modeset
blacklist nvidia-uvm
blacklist ipmi_msghandler
blacklist ipmi_devintf

So I thought I had blacklisted it but it seems I did not. Since I do not
want to use it maybe it is better to check if the lock up occurs with
nouveau blacklisted. I will try that now.

I did. See above.

Can you try if you would get more out of it using netconsole?

I blacklisted nouveau and booted into a 6.1 kernel:
% uname -a
Linux xps 6.1.0-9-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.27-1 (2023-05-08) x86_64 GNU/Linux

It has been running without problems for nearly two days now:
% uptime
 08:34:48 up 1 day, 16:22,  2 users,  load average: 1.33, 1.26, 1.27

Regards,

Nick.

Thanks, that makes a lot more sense now.

Nick, Can you please test if nouveau works with runtime PM in the
latest 6.4-rc?

If it works in 6.4-rc, there are probably nouveau commits that need
to be backported to 6.1 LTS.

If it's still broken in 6.4-rc, I believe you should file a bug:

https://gitlab.freedesktop.org/drm/nouveau/


Lyude, Lukas, Karol

This thread is in relation to this commit:

24867516f06d ("ACPI: OSI: Remove Linux-Dell-Video _OSI string")

Nick has found that runtime PM is *not* working for nouveau.

If you recall we did 24867516f06d because 5775b843a619 was
supposed to have fixed it.

keep in mind we have a list of PCIe controllers where we apply a
workaround: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/nouveau/nouveau_drm.c?h=v6.4-rc4#n682

And I suspect there might be one or two more IDs we'll have to add
there. Do we have any logs? And could anybody test if adding the
controller in play here does resolve the problem?

There's some archived onto the distro bug.  Search this page for "journalctl.log.gz"

interesting.. It seems to be the same controller used here. I wonder
if the pci topology is different or if the workaround is applied at
all.

But yeah, I'd kinda love for somebody with better knowledge on all of
this to figure out what exactly is going wrong, but everytime this
gets investigated Intel says "our hardware has no bugs", the ACPI
folks dig for months and find nothing and I end up figuring out some
weirdo workaround I don't understand. And apparently also nobody is
able to hand out docs explaining in detail how that runtime
suspend/resume stuff is supposed to work.

I have a Dell XPS 9560 where the added workaround in nouveau fixed the
problem and I know it's fixed on a bunch of other systems. So if
anybody is willing to publish docs and/or actually debug it with
domain knowledge, please go ahead.

yeah, but I also couldn't see a log with the usual nouveau messages,
so it's kinda weird.

Anyway, the output of `lspci -tvnn` would help

So the bridge it's connected to is the same that the quirk *should have been* triggering.

May 29 15:02:42 xps kernel: pci 0000:00:01.0: [8086:1901] type 01 class 0x060400

Since the quirk isn't working and this is still a problem in 6.4-rc4 I suggest opening a
Nouveau drm bug to figure out why.

Re: Regression from "ACPI: OSI: Remove Linux-Dell-Video _OSI string"? (was: Re: Bug#1036530: linux-signed-amd64: Hard lock up of system)

[Linux regression tracking (Thorsten Leemhuis)]

Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting
for once, to make this easily accessible to everyone.

Nick, what's the status/was there any progress? Did you do what Mario
suggested and file a nouveau bug?

I ask, as I still have this on my list of regressions and it seems there
was no progress in three+ weeks now.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

It was not apparent that the suggestion to open "a Nouveau drm bug" was
addressed to me.

I have not pursued this further since as far as I could tell I already
provided all requested information and I don't actually use nouveau, so
I blacklisted it.

Nick.

I wish things were earlier for reporters, but from what I can see this
is the only way forward if you or some silent bystander cares.

I doubt any developer cares enough to take a closer look[1] without a
proper nouveau bug and some help & prodding from someone affected. And
looks to me like reverting the culprit now might create even bigger
problems for users.

Hence I guess then this won't be fixed in the end. In a ideal world this
would not happen, but we don't live in one and all have just 24 hours in
a day. :-/

Nevertheless: thx for your report your help through this thread.

We recently merged this commit:
https://gitlab.freedesktop.org/drm/nouveau/-/commit/11d24327c2d7ad7f24fcc44fb00e1fa91ebf6525

It might resolve the problem. Worth testing at least, but I can't
remember if this was a hybrid AMD/Nvidia system, but I think it was?

In principle I can open another bug report, but I don't know how or
where to report "a Nouveau drm bug". Please keep in mind that I'm just
an end user. I learnt to use git bisect specifically because of this
bug. Prior to that, I hadn't compiled a kernel in about 15 years.

If someone can point me to some docs about for reporting nouveau bugs I
can look into it.

This is a very common Dell XPS 15 7590 so I expect many people could
experience this issue. Or maybe like me they only use the intel GPU.

No problem. I am willing to try to do more, but right now I don't know
how to do what has been suggested.

Cheers,

Nick.

I reported this twice already. I guess it was lost since for some
reason emails in this thread are not being trimmed. I'll repeat here:

I did eventually see a lockup of this kernel. On the console I saw:

[  151.035036] vfio-pci 0000:01:00.0 Unable to change power state from D3cold to D0, device inaccessible

I did not see the other two lines that were present in earlier lock ups.

Regards,

Nick.

Gotcha, I guess keep me updated since it seems like things -might- be working
from what I gathered here? Happy to look further if they find that 6.4-rc is
broken though
