Hi! Since kernel 6.0.18 resume from hibernate fails, the system hangs and a hard reset is necessary. The CPU is a Ryzen 5600G, the system is Linux From Scratch-11.1.
I found this in the system log:
[...] Jan 12 19:30:03 LUX kernel: [ 50.248036] amdgpu 0000:30:00.0: [drm] *ERROR* [CRTC:67:crtc-0] flip_done timed out Jan 12 19:30:03 LUX kernel: [ 50.248040] amdgpu 0000:30:00.0: [drm] *ERROR* [CRTC:70:crtc-1] flip_done timed out Jan 12 19:30:14 LUX kernel: [ 60.488034] amdgpu 0000:30:00.0: [drm] *ERROR* flip_done timed out Jan 12 19:30:14 LUX kernel: [ 60.488040] amdgpu 0000:30:00.0: [drm] *ERROR* [CRTC:67:crtc-0] commit wait timed out ^@^@^@^@^@^@^@^@^@^[...]@^@^@^@^@^@^@^@^@^@^@^@^@^@Jan 12 19:31:20 LUX syslogd 1.5.1: restart.

Bisecting the problem turned up this:

drm/amdgpu: make display pinning more flexible (v2)
commit 81d0bcf9900932633d270d5bc4a54ff599c6ebdb upstream.
Only apply the static threshold for Stoney and Carrizo. This hardware has certain requirements that don't allow mixing of GTT and VRAM. Newer asics do not have these requirements so we should be able to be more flexible with where buffers end up. [...]
Let me know if you need more info. Thanks.
