Description Shawn Starr 2016-05-22 18:27:20 UTC

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.

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.
