Public bug reported:

Product: Ubuntu 22.04

Component: Kernel 6.5.0-35-generic

Summary: The kernel 6.5.0-35-generic in Ubuntu 22.04 fails to load the
LVM module, causing the root file system to not be found and the system
to boot into (initramfs).

Steps to Reproduce:

Install Ubuntu 22.04 with kernel 6.5.0-35-generic.
Set up a root file system using LVM.
Reboot the system.

Expected Results: The system should boot up normally with the root file
system loaded correctly.

Actual Results: The system fails to load the LVM module, causing the
root file system to not be found. As a result, the system boots into
(initramfs).

Additional Information: This issue seems to be specific to kernel

this problem.

Workaround: Reverting to kernel 6.5.0-28-generic boots the system
normally.

Priority: High - affects basic system functionality.
