            Bug ID: 216119
           Summary: 087451f372bf76d breaks hibernation on amdgpu Radeon R9
                    390
           Product: Drivers
           Version: 2.5
    Kernel Version: v5.17+
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: h.judt@gmx.at
        Regression: No

This is a problem with amdgpu only, as I did not experience this on my other
machines, and caused by [087451f372bf76d971184caa258807b7c35aac8f] drm/amdgpu:
use generic fb helpers instead of setting up AMD own's

Reverting this patch makes me a happy amdgpu user with working hibernation
again on Linux 5.18.3.

Note I did the bisect on the stable linux repo, but that shouldn't matter.
