Bug ID: 100141 Summary: [AMDGPU][CIK][4.10/4.11-rc1] Regression - Hibernation does not respect 'reboot' option in /sys/power/disk 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
AMDGPU used to respect rebooting after hibernation, now when you specify this, it performs writing pages to disk then freezes.
If I perform a hard power off then back on, hibernation will resume correctly.
Please test for 'reboot' when using /sys/power/disk
