            Bug ID: 111729
           Summary: RX480 : random NULL pointer dereference on resume from
                    suspend
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)

            Status: NEW
          Severity: major
          Priority: not set

Syslog data

Since kernel 5.2.x, resuming from suspend will randomly crash amdgpu/drm with a
black screen. After login via SSH, rebooting or halting the host will not
complete. A hard reset becomes unavoidable. Currently using 5.3.0-rc8, RX 480
with one single display. Stable 5.2.x kernels don't resolve the issue. The host
does not last a week without a forced reboot.

Please see the attached syslog trace. Thanks.
