journalctl from the boot

When booting, my system hang at "fb: switching to amdgpudrmfb from EFI VGA"
I could SysRq and also ctrl-alt-del it, but I couldn't get anything more on the
screen.

Turns out I couldn't load my firmware anymore. My filesystem (or is that
ramdisk on Ubuntu) had been corrupted somehow.

failed
aug 28 23:45:18 mammut kernel: amdgpu 0000:0a:00.0: Fatal error during GPU init

It would be super nice if the system could go back to VGA mode so I could see
the error in this case.

Kernel 4.18, Ubuntu, FIJI. amdgpu.dc=1/0 didn't make any difference...
