Yes! I've been thinking the same. We already have bug 1965303 to track
that. But I find it curious that device_timeout=0.1 didn't fix it fully
because that should have the same effect as using SimpleDRM to avoid
waiting for i915/amdgpu startup.

I need to find out if Plymouth's initrd support exists for shutdown
splashes only or is also meant to be useful in startup. If the latter
then it seems to be broken.

Yes I do need to double-check if hacking out
PLY_ENABLE_SYSTEMD_INTEGRATION affects the presence of those specific
messages.

Title:
  Annoying boot messages interfering with splash screen

Status in plymouth package in Ubuntu:
  In Progress

Bug description:
  Since upgrading from 20.04.6 Desktop to 22.04, the boot screen is not
  as clean as it used to be.

  Basically, the flow used to be in 20.04:

  GRUB > Splash screen > Login prompt

  Currently in 22.04:

  GRUB > Splash screen > Messages (in the attached file) > Splash screen
  again for a sec > Login prompt

  All of those messages already existed in 20.04, the difference is that
  they were not appearing during boot.

  I was able to get rid of the "usb" related messages by just adding
  "loglevel=0" in GRUB. Currently is "quiet loglevel=0 splash".

  Regarding the fsck related message, I can get rid of them by adding
  "fsck.mode=skip".

  However, I do not want to just disable fsck or set the loglevel to 0.
  This is not a sustainable solution.

  Something definitely changed here. These messages are not of enough
  relevance to be shown at boot by default, and they should remain
  hidden like they were in Focal.

  Obviously a minor issue, but important to the whole look and feel of
  the OS for desktop.
