This is the disk that timesout on the boot - I see this in the journalctl every so often - where is this coming from?

You mention this, thus you probably think it may be important. But in fact you tell nothing about it. Or do you think that we all know how you “restore as usual”?
When this is about a system restore after a disaster, it may be that you restored that /dev/disk/by-uuid/9cbad955-9531-4ece-b6fd-e4cf8ca26b8a as a string in some configuration.
Maybe
cd /etc
grep 9cbad955-9531-4ece-b6fd-e4cf8ca26b8a *
And of course, you talk about blkid ands /etc/fstab, but you show nothing! To say it bluntly: we do not believe you, we only believe what the computer shows.
I was still looking for the source - It is the swap file but it is not starting at boot - I have to swapon /dev/nvmen0p3 for it to show and it is not there on a reboot.
I was doing my monthly bare iron restore - I put a new nvme drive in and make a gpt and the 3 files system and change the UUID’s for the ext4 and swap mount the new filesystems as /mnt and create the missing directories not backed up (dev run sys tmp proc boot and boot/efi ) and tar xvf the backup - I have done this every month for 15 years - this is the first time anything different has happened. I see that /boot/efi/EFI/boot has different files than the last time I restored a backed up. I do not have secureboot - just opensuse - so I have to grub2-install anytime I use the recovery USB that has a built 15.2 with MATE.
