Created attachment 139474 [details] 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. I use amd-staging-drm-next as of today with as last commit commit 905aa01b240f9216b6dbba3226bf10b2d96eebb7 (origin/amd-staging-drm-next) Author: Colin Ian King <colin.king@canonical.com> Date: Wed May 2 15:43:16 2018 +0100 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.
