Ubuntu 22.04 unable to mount root partition

[Nicholas Demosthenous]

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.

After a clean install of Ubuntu 22.04, I have the same issue on an Acer Spin 5 SP513-54N-74V2. Installing and booting into kernel 5.13.19 works fine and resolves the issue. With kernel 5.15 and no "pci=nocrs," the error seems to be i2c_designware: failed to claim resource.

[André Almeida (ploquets)]

Tried to install 5.17.4-051704 and the same boot issue happened.
So, even with newer kernel the problem is ocurring.

I can confirm kernel 5.13.19 works with 'pci=nocrs'.

[Andres Marin Perez (amphagguever)]

I have exactly the same problem on a Lenovo IdeaPad 3 14IIL05. I don't know if it is of any help but this is the touchpad's info:

cat /proc/bus/input/devices

MSFT0001:01 06CB:CE2D Touchpad

[TheTakylo (thetakylo)]

Same for my lenovo IdeaPad 5 14IIL05, cant boot with "pci=nocrs" that is required to make the touchpad work.
it was very well working on ubuntu 20.04, 21.04 and 21.10

cat /proc/bus/input/devices

MSFT0004:00 06CB:CD98 Touchpad

[pstassinos (pstassinos)]

Same problem here with Lenovo. "Pci=norcs" after upgrade to 22.04 is not working. Also can not boot any more. I make a fresh install voyager ubuntu 22.04 but I can not use touchpad.i am with a mouse. Any solution?

[Nicholas Demosthenous (demosnk)]

@pstassinos (pstassinos) As a workaround try installing kernel 5.13.19 from https://kernel.ubuntu.com/~kernel-ppa/mainline/

[Rick Tu (ricktu)]

I tried Ubuntu 22.04 with kernel 5.13 on Acer Spin 5 SP513-54N. Touchpad, touchscreen, and stylus all work, but Wi-Fi does not work.

[Nicholas Demosthenous (demosnk)]

Things are back to normal in kernel version 5.18. Laptop boots normally and touchpad works!

[Haresh Samnani (harry6x)]

Are you confirming that in this version: 5.18.0-051800 things are back to normal?

[Nicholas Demosthenous (demosnk)]

@ Haresh Samnani (harry6x): Yes, for me things are back to normal. The laptop boots up normally and the touchpad works normally as well.

[Brad Jolly (nisitiiapi)]

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

[Haresh Samnani (harry6x)]

Thanks alot!

[Andres Marin Perez (amphagguever)]

Just to let you know, I upgraded to Ubuntu 22.04.1 with kernel 5.15.0-47 and the problem is gone. The touchpad now works correctly

[Nicholas Demosthenous (demosnk)]

Thanks, I have changed the status to 'fix released'.
