Got it! Zeroing swap partition and reformatting it - looks like that problem fixed:
$ cat /proc/swaps Filename Type Size Used Priority /dev/sda5 partition 5242876 0 -1 $ ls -la /dev/disk/by-uuid/ | grep sda5 lrwxrwxrwx 1 root root 10 2012-03-18 15:20 cf32f967-d4a9-4904-a9e7-498af72339d4 -> ../../sda5 $ sudo swapoff -a $ sudo dd if=/dev/zero of=/dev/sda5 bs=4M $ sudo mkswap -L SWAP -U cf32f967-d4a9-4904-a9e7-498af72339d4 $ sudo reboot So, I guess that problem was in corrupted data on swap partition from previous swap image(s), so kernel just couldn't process it correctly while resuming. Now hibernation should be working correctly. I hope that this information will be useful for others. ** Changed in: linux (Ubuntu) Status: Confirmed => Opinion -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/957999 Title: No hibernation after reallocation of root and swap partitions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/957999/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
