Alex, thanks for the new firmware. Still Bios recognition errors at boot, but otherwise ok.

[ 3.461112] [drm] BIOS signature incorrect 20 7 [ 3.461117] amdgpu 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff

This is harmless. The driver tries several methods to fetch the vbios image. The driver would not load at all if it failed to fetch the vbios image.
