Hi Joerg,
how embarrassing. Indeed, somehow my patching didn't work. But I'll better it
today :-) and report back.
The Mainboard of this machine is
Micro-Star International Co., Ltd. MS-7C94/MAG B550M MORTAR (MS-7C94), BIOS
1.94 09/23/2021
and the CPU is
Vendor ID: AuthenticAMD
Model name: AMD Ryzen 7 5700G with Radeon Graphics
CPU family: 25
Model: 80
Thread(s) per core: 2
Core(s) per socket: 8
Socket(s): 1
Stepping: 0
Regards,
Jörg.

Are you sure you tested the right kernel? My patch removes that warning,
so it can't trigger anymore. It also adds a new warning, but in
different file and line.
In 'kern.log' I also found this:
May 2 21:53:27 xxx kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx
timeout, signaled seq=16, emitted seq=17
GPU errors, hard to say what triggered this. Can you please send me your
exact MB and CPU model? There is a chance this is firmware-related.
Besides that I learned that on some systems this warning only triggers
on resume. So increasing the timeout seems to be the only viable fix.
Can you please try the attached diff? It also prints the time it took to
enable the GA log.
Regards,
Joerg
