            Bug ID: 97123
           Summary: [AMDGPU][CIK] Suspend to disk deadlocks system on
                    resume always (Linus master + drm-next-4.9-wip)
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: shawn.starr@rogers.com

I've been testing AMDGPU with CIK (Bonaire), in drm-next-4.8-wip /
drm-next-4.8, hibernation sometime worked sometime not.

With drm-next-4.9-wip (with Linus master merged), hibernation works, resume
fails after image is loaded, system is deadlocked.

Is there any debugging I can do testing path?

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.

[PATCH 2/3] drm/amd/amdgpu: sdma resume fail during S4 on CI 
[PATCH 3/3] drm/amd/amdgpu: compute ring test fail during S4 on CI

With patch #2 specifically not upstream yet, the corruption with the image
attached is now gone on subsequent freeze()/thaw() cycles.
