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.

Tried as well in (initramfs) to load the kernel module for lvm and lvm vgchange -ay but this does nothing in (initramfs) making the system also not recoverable when starting with the 6.5.0-35-generic kernel

Was able to 'solve' the issue through

sudo apt-get purge linux-image-6.5.0-35-generic

reboot # into the 6.5.0-28-generic kernel

sudo apt update;sudo apt upgrade

reboot # into the 6.5.0-35-generic kernel
