[Bug 2031366] Re: [Ubuntu][Jammy][Desktop] Can't get into the desktop after installing Ubuntu 22.04

[KUN-YANG FAN]

Hi We did some test and found

We can install 20.04 FOCAL Desktop kernel 5.15.0-79 and reboot into the Desktop. 
And try to upgrade to 22.04 with same kernel version but we can't boot into Desktop and stuck in the initrd   
mode with prompt "(initramfs)". 
It seems the difference is the raid tool something because the device mapper file /dev/dm-1 (EFI parttion) and /dev/dm-2 (root partition) doesn't exist. Is any way we can rollback the RAID tool in 22.04 to 20.04?
