Public bug reported: 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. ** Affects: ubuntu Importance: Undecided Status: New ** Summary changed: - Kernel 5.15 and later doesn't mount root partition + Kernel 5.15 and later doesn't mount root partition (Ubuntu 22.04) ** Summary changed: - Kernel 5.15 and later doesn't mount root partition (Ubuntu 22.04) + Ubuntu 22.04 unable to mount root partition -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970056 Title: Ubuntu 22.04 unable to mount root partition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1970056/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
