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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/50437 Title: Resume from hibernation may fail because swap partition UUID does not match /etc/initramfs-tools/conf.d/resume -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
