[Bug 2091753] Re: Plymouth fails with kernel 6.8.0-50

I can confirm that workaround with a small change for AMD integrated
graphics. Instead of "i915", I added "amdgpu" to /etc/initramfs-
tools/modules and do the respective commands.

Thanks @rfaull for figuring this out!

Title:
Plymouth fails with kernel 6.8.0-50

Status in linux package in Ubuntu:
Confirmed

Bug description:
Plymouth fails to fully boot with this kernel when asking for
encryption password for local partition. The system freezes and can be
recovered in rescue mode. Previous kernels accepted the password and
continued to X as expected.

Remove 'splash' from GRUB_CMDLINE_LINUX_DEFAULT="quiet" prevents
plymouth from loading and booting continues to X after password is
entered in when booting pauses and asks for the password in the
terminal.

This behaviour is true on laptops running Linux Mint (Wilma) and
Ubuntu KDE 24.04 with encrypted partitions.

On devices without encrypted partitions 'quiet splash' is included on
the kernel command line and booting proceeds as expected.

Ubuntu 6.8.0-50.51-generic 6.8.12
Description: Linux Mint 22
Release: 22
