            Bug ID: 95526
           Summary: [AMDGPU][CIK] Suspend to disk deadlocks system (never
                    worked)
           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

Current kernel: 4.7.0-0.rc0.git2.3.fc23.x86_64 with CIK enabled in AMDGPU.

If I use the following command:

echo disk > /sys/power/state

The laptop deadlocks and never attempts to freeze/write memory to disk.

This has never worked for me with AMDGPU with CIK enabled, so I don't know if
there's a point to bisect from.

--- Comment #1 from Shawn Starr <shawn.starr@rogers.com> ---
Tested: Sun Jun 5 commits from agd5f's drm-next-4.8-wip

Suspend to ram works: echo mem > /sys/power/state
Suspend to disk works: echo disk > /sys/power/state
Restoring from suspend disk image worked.

This can be closed now.
