dmesg
Reproduce:
- boot
- Start X
- Stop X
- cat /sys/kernel/debug/dri/2/amdgpu_gpu_recovery
- Wait till finished
- Start X
- Notice slowness
- Stop X
The dmesg says that the reset failed, but the screen comes back with some artifacts. drawing in X is very slow event though pp_dpm_sclk seems to be indicating reasonable speeds.

drm/amd/display: clean up assignment of amdgpu_crtc
The declaration of pointer amdgpu_crtc has a redundant assignment to
amdgpu_crtc. Clean this up by removing it.

plus a patch of my own adding some more dev_info messages to the reset process.
