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.
