--- Comment #3 from Tom Seewald tseewald@gmail.com --- Installed the new Polaris firmware released on December 3rd, however that doesn't appear to affect my card as the content of /sys/kernel/debug/dri/1/amdgpu_firmware_info is unchanged.
Upgraded to Mesa 18.3.0 from 18.2.4 - no change.
Added dmesg of 4.20-rc5 with drm.debug=0xe, showing the hang. It now prints hung kernel tasks backtraces rather than "[drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser -125!".
I've also included the power management information before and after the GPU hang.
