System hangs after "fb: switching to amdgpudrmfb from EFI VGA".
How long have you waited for? E.g. if a microcode file is missing, the attempt to load it can hang for one or several minutes before timing out.
Waited for ~5min now, but nothing changed.
I am unable to obtain any logs of the crash (LUKS encryption might be the reason?).
One possibility is to prevent the driver from loading by passing
modprobe.blacklist=amdgpu
on the kernel command line, then you can try manually loading it with
sudo modprobe amdgpu
and should get the full dmesg output.
Thank you, this worked. Full output is attached, but appears fine. Still, the video output freezes.
