Public bug reported:
When trying to boot either of the 2 kernel versions above, the computer
displays the "Kubuntu" logo for a minute or so, then goes to a text
"(initramfs)" prompt. It appears to be unable to see my SSD correctly
(despite grub just loading from it!), as "ls /dev" shows only "nvme0",
not "nvme0n1".
The last working kernel version for me is 5.4.0-42.
I have already seen others that report this same bug, but with different
m2 nvme. The fix from 5.4.0-48 did not work for this instance.
