            Bug ID: 108685
           Summary: Raven Ridge: VMC page fault on resume from suspend
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu

kernel log with lockup on resume

This is using 4.20.0-rc1-2.g0587eb8. I believe this is the issue I have had=
 in
the past where the system does not resume from suspend, or at least the
graphics are locked up when I do.

I am able to fix these resume from suspend gpu lockups by using a script to
disable C6 states on the CPU before suspend and then enabling C6 states on
resume (this uses zenstates.py to set MSR through a systemd sleep script).
