Comment 76 for bug 508516

Hmmmm... I added the file /etc/pm/config.d/00sleep_module after I installed uswusp. The file contains the line "SLEEP_MODULE=uswsusp". I cannot recall why I did this (possibly because of info in http://www.ubuntugeek.com/fix-for-suspend-and-hibernation-problem-for-laptops.html).

Maybe this is why your hibernate does not work. When I commented out that line in the file, my machine refused to hibernate and froze up so that I had to hard reboot. Sorry about forgetting that. Too many things to remember! :-)
