dmesg
Reproduce:
1) boot
2) Start X
3) Stop X
4) cat /sys/kernel/debug/dri/2/amdgpu_gpu_recovery
5) Wait till finished
6) Start X
7) Notice slowness
8) 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.
