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.
