I've the same problem and was partially solved recreating swap partition and changing fstab + /etc/initramfs-tools/conf.d/resume
I'm able to hibernate when Ubuntu is at GDM login screen but if I try to hibernate when gnome is active (session initiated) the hibernation fail, never resume, recovered only turning off and some times removing batteries. The are several file system problem after restarted.
