Previously resume consistently produced this output with a subsequent crash of the X-server: [ 7025.164024] radeon 0000:01:00.0: ring 5 stalled for more than 10000msec [ 7025.164030] radeon 0000:01:00.0: GPU lockup (waiting for 0x000000000000000a last fence id 0x0000000000000002 on ring 5) [ 7025.164034] [drm:uvd_v1_0_ib_test] *ERROR* radeon: fence wait failed (-35).
