Comment 3 for bug 1877889

Since logging this bug entry, I suffered a corrupted root filesystem. I don't know for sure that the hanging on boot followed by me forcing reboots was the cause, but I guess it won't have helped. :/ I guess my SysRq S+U+S+B didn't work quite as well as I'd thought.

I was unable to recover the filesystem so I've had to reinstall Ubuntu 20.04. Luckily it was just the root filesystem that was lost so a reinstall was quite straight forward.

I don't expect that a reinstall will have fixed the hangs (my kernel version is precisely the same as before), so I'll update when I see them again.
