            Bug ID: 204683
           Summary: amdgpu: ring sdma0 timeout
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.3.0-rc5
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: mh at familie-heinz.name
        Regression: No


when playing some games I randomly (sometimes after 5 minutes, sometimes after
2 hours) get a blank screen, sometimes audio still works, sometimes the whole
system locks up. I've seen this with Rise of the Tomb Raider and 7 Days to Die
so far.

I finally managed to sync the log files to disk to get an error, before whole
thing locked up:

sdma0 timeout, signaled seq=368056, emitted seq=368057

Aug 24 11:13:33 egalite kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring
gfx timeout, but soft recovered

Only a hard reset made me recover from that.

This is with a self-built kernel 5.3.0-rc5. Also happens with 5.2.1.
Mesa: 19.1.4-1
GPU: Vega 56
