            Bug ID: 197851
           Summary: Resume from suspend sometimes results in black screen
                    on Radeon R5
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.14.0-041400rc8-generic
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: sonarsoundapplications at gmail.com
        Regression: No

As stated in the description, resuming from suspend will occasionally result in
the screen remaining black until hard reset. I have pressed all of the keys,
clicked the mouse, and even held the power button for varying lengths of time.
It isn't just limited to screen lid closing either. Screen timeouts and manual
suspend also feature this issue. I saw a similar bug for a rx480 but figured
since it's a different GPU, it may need its own bug report. Feel free to merge
the issues if you think I am incorrect.
