A long term "gave up waiting for suspend/resume device" problem

[Chris Green]

My main desktop machine is a Fujitsu Esprimo P910 currently running
xubuntu 22.04.

It has quite a few disk drives in it:-

    Filesystem     Type 1M-blocks   Used  Avail Use% Mounted on
    /dev/nvme0n1p2 ext4     48122  12345  33262  28% /
    /dev/nvme0n1p3 ext4    896121 318163 532367  38% /home
    /dev/sdb1      ext4    937804 294646 595450  34% /bak
    /dev/sda1      ext4      9980    168   9284   2% /boot
    /dev/sda2      ext4    109536  64903  39025  63% /scratch

/dev/nvme0n1p1 is supposed to be swap space but I'm not sure if it's
actually working as such or not.

The Fujitsu BIOS doesn't see the NVME drive which is why /boot is on
/dev/sda1 (which is a SATA SSD) so that /boot is visible at power-up.

The system boots fine at power-up but fails to reboot, when one
reboots it just flashes the pre-boot screen up, then goes blank for
quite a while and finally displays the dreaded "gave up waiting for
suspend/resume device" message.  If you power off and power up again
the system boots OK.

This problem started when I upgraded from xubuntu 20.04 to 22.04, the
system rebooted fine (with the same disks) in 20.04 and previous
versions.

I'm wondering what's going to happen when I upgrade (in a few months
time) to 22.04.

It would be good to find a fix to the reboot problem before upgrading
though.

I suppose I could move to a new system whose BIOS recognises NVME disk
drives but it's difficult to find low power consumption desktop
systems. The Fujitsu Esprimo P910 consumes less then 20 watts when
idle and as it's on all the time (it's a server as well as a destop
system) that's important for me.

Any/all ideas very welcome, both for fixes to my reboot problem and
for new system hardware.
