Suspend/resume regression?

[Mihai Moldovan]

Hi


I am very sorry to bring that up again, after
https://bugzilla.kernel.org/show_bug.cgi?id=214179 and
https://bugzilla.kernel.org/show_bug.cgi?id=215103 , which supposedly fixed
issues like this, but I am still seeing crashes on suspend and resume operations
(although I've only ever tested with 6.1.1 and the newest firmware).

I am using a Clevo P7xxDM2-G laptop.

Kernel log ring buffer excerpt (modified to leave out unnecessary details, but
can also provide the full one):

[...]

At this point, I tried the usual workaround and rmmod ath11k_pci, which
naturally hang. I'm not sure if it recovered eventually after quite some
minutes, or whether I persuaded it into working by resetting the PCI link via
/sys/bus/pci/devices/0000:70:00.0/reset.

Either way, it eventually worked, I could re-load the module and it has been
working ever since.

I can also provide an ACPI dump of my system if needed.


Best regards,




Mihai
