Comment 2 for bug 681877

Hibernating and resuming seems to work fine on a Latitude E6410 running Natty, tested with image 20101130. However, after resuming, the swap partition changed and the UUID no longer matches the one in /etc/fstab. So, the hibernate option is no longer available in the panel drop down menu. After recovering the swap partition, hibernation seems to work fine again but the same happens to the swap partition.

On a side note, suspend doesn't resume with the swap partition. However, after hibernation and the swap gets removed, then suspend resumes just fine. I tried this a couple times and the behavior is consistent: suspend with swap doesn't resume.
