Comment 10 for bug 1094595

Clayton: Please test with cryptswap disabled. While some have reported that they have cryptswap working with hibernate (such as https://help.ubuntu.com/community/EnableHibernateWithEncryptedSwap), it's not supported by Canonical or Dell and, if misconfigured, may prevent hibernation from working correctly.

John: Please paste the contents of /etc/fstab on your system.
