I have a bit more information on my failed restart.

It's "losing" one of the disk drives!  If I leave the system long
enough after a restart I get the following messages:-

    Gave up waiting for suspend/resume device
    Common problems:
       -Boot arge (cat /proc/cmdline)
          - check rootdelay= (did the system wait long enough?)
          - missing modules (cat /proc/modules; ls /dev)

    ALERT: UUID=2d6ff70c-1894-4afa-a35c-5abb40549d3b does not exist.
    Dropping to a shell!


It's not surprising it's failing to reboot, UUID=2d6ff70c-1894-4afa-a35c-5abb40549d3b
is my / drive.


The question is why did it work in 21.10 and now doesn't work in
22.04, and why does power cycling make the drive reappear?  What
probably complicates things rather is that the drive is an NVME SSD and
isn't visible to the BIOS.

My system's /boot is on a different drive which is visible to the BIOS
and, after booting, Linux can 'see' the NVME SSD.
