Created attachment 145576 [details] journalctl last boot kernel message
Can u retry with latest FW from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
Still same issue.
and also load kernel with drm.debug=1 as there seems a failure in PSP command submission during FW loading but the actual code of failure is now under debug log level.
I can reproduce the issue on latest firmware ("amdgpu: update vega20 ucode for 19.30") and latest amd-staging-drm-next ("drm/amdgpu: remove redundant variable r and redundant return statement").
I don't see keep trying latest kernel/firmware makes us going anywhere. If you need a physical hardware to debug, please just let me know.
