Hi dibl
Thanks for the ideas.
The machine has been running siduction for many years, hasn't changed a bit. It has a rack mount for the HDD. I have 4 disks that I can easily slip in, one with windows 10, one with siduction, one with Leap and one with Tumbleweed. anyway ...
The UUID in fstab, for root, is the same as the one showing in the error. Works with 5.14, errors out with 5.15. I have all the normal partitions /root, /home & swap.
I'm going to see if I can find something in the logs, Eventually the answer will turn up.
Tom
