[Bug 1970056] Re: Ubuntu 22.04 unable to mount root partition

After testing kernel 5.18.0 from mainline, the issue does appear
resolved -- the system will boot with "pci=nocrs" and the touchpad,
touchscreen function.

Title:
Ubuntu 22.04 unable to mount root partition

Status in linux package in Ubuntu:
Confirmed

Bug description:
After updating from Kubuntu 21.10 to Kubuntu 22.04, boot drops to a
(initramfs) prompt/busybox. When I type "exit" I get the "Gave up
waiting for root file system device" error message and "ALERT!
UUID=[nvme drive UUID] does not exist. Dropping to a shell!"

I can still boot into KDE when selecting the older kernel version
5.13.0-40-lowlatency. I have tried the newer kernel versions
5.15.025-generic, 5.15.0.24-lowlatency, 5.17.4-051421-generic and
5.14.21-051421-lowlatency and all have produced the same problem.

When removing the the "pci=nocrs" kernel paramater in Grub for these
newer versions, the system boots into KDE but the touchpad does not
work. Kernel version 5.13.0-40-lowlatency boots into KDE without
removing the "pci=nocrs" parameter and everything works as expected,
including the touchpad.

My hardware is a Lenovo ideapad lenovo ideapad 3 15IIL05, Processors: 8 × Intel® Core™ i5-1035G4 CPU @ 1.10GHz, Memory: 7,3 GiB of RAM, Graphics Processor: Mesa Intel® Iris® Plus Graphics. I have upgraded the hard drive that came with the machine to a Kingston SA2000M8500G 465,8GiB nvme drive.
