Update kernel-firmware-amdgpu from 20200610-1.1 to 20200702-1.1 breaks video on a HP ProBook 455R G6 containing an AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx, i.e. AMD Raven Ridge.
The problem manifests itself as a blank screen when the boot splash would be displayed and continuously spinning system fan. The machine is unresponsive when reaching this state, i.e. escape and sysrq keys are not working.
Downgrading just the kernel-firwmare-amdgpu packages works around the issue.
There is one kernel log message only visible with the new firmware:
kernel: amdgpu 0000:05:00.0: [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* IB test failed on gfx (-110).
