[Bug 2103798] Re: go backtrace during boot, can't boot

[Alessandro Astone]

SimpleDRM is built into the kernel binary rather than as a module, so
there should be no extra modules needed.

The fact that `dracut --force --add-drivers "=drivers/gpu/drm/tiny
vboxvideo virtio-gpu"` makes it work on real hardware like intel or amd
I find quite odd.

What was the output before dracut --add-drivers?

Title:
  go backtrace during boot, can't boot

Status in dracut package in Ubuntu:
  New

Bug description:
  I'm using dracut with plucky. When I reboot, I briefly see the
  passphrase prompt for the disk encryption, but I don't have time to
  type it completely. Midtype, the screen gets filled with a golang
  backtrace, and boot stops.

  The only way to boot this system (that I have found) is to edit the
  grub entry and remove "quiet splash".
