Tested with 3.11.0-2-generic: works.

*however*, I had to take care to manually select the same kernel I was
running at hibernation time in the Grub boot menu.

This may be what happened last time: a new kernel got installed, then I
hibernated my machine and grub picked the new kernel.

In Fedora, when you hibernate your system, on the next boot grub skips
the menu and automatically boots the same kernel that was used before.

Additionally, I feel that the user should be shown an error message when
dehibernation failed. I was puzzled when I got a lightdm login screen
instead of my old session.
