I didn't spot anything relevant in /var/log/dmesg or /var/log/ > syslog. Could you post yours so that I know what to look for pleae? I'll see if I can get any useful dmesg output next time I resume. You mentioned running update-initramfs - forgive a dumb question, but did you do that after configuring uswsusp? I see that I have a file /etc/initramfs-tools/conf.d/resume, containing the line: RESUME=UUID=4b33b853-b245-4ec1-b649-c14f9a9b9907 Do you have such a file, with similar contents?

Glad we got it sorted out, but I wonder why that file wasn't automatically created. I'm pretty sure that I never had to do it manually.
