Hi,
On a Debian 12 ("bookworm") system, I observed a new warning when I
upgraded from kernel 6.1.25 to 6.1.27. This is on a system with an RX
6800 XT GPU and 3500X processor.
I've traced it down to commit c8b5a95 ("drm/amdgpu: Fix desktop freezed
after gpu-reset"). Rebuilding the 6.1.27 kernel without this change
makes the warning disappear.
I can reliably trigger this (and another) warning with
$ sudo cat /sys/kernel/debug/dri/0/amdgpu_test_ib
run ib test:
ib ring tests passed.
5 or 6 seconds after this, two warnings are printed. I see these same
two warnings on system shutdown (or, at least, they looked similar
enough to the above that I didn't check for identity).
I've attached
(1) the dmesg output after modprobe'ing amdgpu
(2) the dmesg output after triggering amdgpu_test_ib
The system in question is only used for ROCm development. I haven't
observed any other side effects there, other than the warning. There's
no monitor attached. So I can't speak to the effect of a desktop freeze.
Best,
