Hi,
I've received a Renesas pcie usb3 card which fails to suspend (to ram)
correctly.
Regular boots appear to be working fine, but upon resuming from
suspend, I get this log:

This is on vanilla 7.0.3. If I add the firmware (renesas_usb_fw.mem,
sha256=177560c224c73...) it fails to load on boot and I get a massive
stall in bootup:

After which the usb root devices are not present (according to lsusb).
Any idea how this can be fixed? I also tried the
https://github.com/markusj/upd72020x-load.git loader, but that didn't
change the situation.
Thanks in advance.

That's waiting 10 seconds with IRQs disabled for USBSTS.CNR to clear.
Sadly, a70bcbc322837 doesn't explain why such long timeout was used.
That being said, this bit should clear, so something is wrong.
Similar 0015 controllers have the RESET_ON_RESUME quirk applied. Sadly
again, the reason isn't documented in all detail we could wish for.
The quirk would apparently try a reset without looking at CNR (which is
frankly a spec violation) and only then test CNR.
Wonder if xhci_hcd.quirks=0x80 boot parameter would make a difference?

That's early boot, presence of FW files shouldn't have any effect.
Perhaps it happens *after* failing to load FW or loading wrong one,
then rebooting without power cycle or something like that?

Adding that quirk to the boot cmdline, caused this on resume:
[ 1357.247864] usb usb10: root hub lost power or was reset
[ 1385.611310] xhci-pci-renesas 0000:03:00.0: PCI post-resume error -110!

and the attached disk is not recognized (obviously).
No stack traces, though.

Looks like the quirk worked, but the chip is still stuck for good.
Sounds like it happens every time?
Does it happen without any connected devices?
Any chance that something goes weird already during suspend?
Maybe try to collect suspend/resume log with extra debug info:
echo 'module xhci_hcd +p' >/proc/dynamic_debug/control
dmesg -W |tee log.txt
# suspend and resume
echo 'module xhci_hcd -p' >/proc/dynamic_debug/control # disable
# stop dmesg, send log.txt
It's odd, I have a uPD720202 (the 2 port variant) and it never had
similar problems. But my card doesn't use the standby supply and
hence it fully power cycles the chip during S3 sleep, so it may be
apples to oranges if your card keeps aux power applied.
Regards,
Michal
