Public bug reported:
After updating to the kernel version 6.8.0-39-generic, my system fails
to boot, displaying the following error messages:
/dev/root: can't open blockdev
VFS cannot open root device /dev/nvme0n1p2 or unknown-block error -6
Please append a correct root= boot option: here are the available partitions:
...
Kernel panic - not syncing VFS unable to mount root fs on unknown-block
Cpu 8pid 1comm ...
Booting into the previous kernel version 6.8.0-38-generic works without
issues.
Steps to Reproduce:
Boot into the latest kernel (6.8.0-39 recovery mode).
Observe the kernel panic and error messages.
Reboot and select the previous kernel (6.8.0-38-generic) from the GRUB menu.
System boots successfully.
