This bug was fixed in the package plymouth - 24.004.60-1ubuntu6
---------------
plymouth (24.004.60-1ubuntu6) noble; urgency=medium
* Cherry-pick upstream fixes for consistent default scale selection
that matches what Mutter chooses on the login screen (LP: #2054769)
* plymouth.hook: Stop automatically re-installing DRM kernel modules in
initrd. initramfs-tools already does this for us in hooks/framebuffer and
should be the authority for which drivers to include.
* Install a /usr/share/initramfs-tools/conf-hooks.d/plymouth with
FRAMEBUFFER=y to make it clear to initramfs-tools that we always want
framebuffer support when Plymouth is installed. (LP: #1970069)

Bug description:
[ Impact ]
Kernel (and systemd) log messages appear during boot for many
machines, when the user should be seeing only the BIOS logo and/or
Plymouth splash screens.
[ Workaround ]
On most machines you can hide the problem by using these kernel parameters
together:
quiet splash loglevel=3 fastboot
[ Original 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.
