Comment 18 for bug 50437

I just came across this problem in Maverick.

I adjusted some of the partitions of my hard drive to create bigger swap partition (so hibernate would work all the time) and in the process had to recreate the swap partition. After rebooting with the adjusted partitions hibernation no longer worked - the computer just started up normally instead of resuming from hibernation.

As suggested in comment #4, following the steps at <https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/66637/comments/23> fixes the problem.
