thank you Cindy-Sue, I did have both of those files but the one with RESUME in it and it did list a mysterious UUID device number (I don't know where it got that as this is a desktop but it does get a lot of dist-upgrades I'll admit) so that's the one I removed and added 'none' in its place.
the other file /etc/initramfs-tools/initramfs.conf didn't mention the resume device, so it had its own file. (maybe I should just remove that file?) anyway, well done you and all the best. -- CK
