--- Comment #2 from Shawn Starr shawn.starr@rogers.com --- With latest patches: [PATCH 3/3] drm/amdgpu: reset the asic when hibernating v2
I am not noticing deadlock on resume, still continue to test.
When hibernating the first time, no corruption occurs on freeze state of display, subsequent hibernations show same corruption pattern on freeze.
When resuming no such corruption shows once the GPU finishes init and we resume successfully.
