Comment 51 for bug 1863672

Completed my testing on the 3 UEFI machines I have that were displaying the symptoms before (2 intel NUCs and one ASUS based UEFI PCs, ranging from 2-cores to 6-cores, and ranging from 2010 to 2020), and I am happy to report that, no matter how many times I boot the system, the 'casper-rw' labelled persistent partition always appears to mount properly.

I have also not seen that "ln: /tmp/mountroot-fail-hooks.d/scripts/init-premount/lvm2: No such file or directory" error manifest itself again, so I am hoping this was just a fluke.

I have however seen the "access beyond end of device" and "I/O error while writing superblock" errors every single time during powerdown/reboot, so I have created https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1871454 for this issue.
