Indeed this sounds like one of the recent cryptswap bugs: bug 1447282, bug 953875 (which are both fixed in -updates) and perhaps bug 1453738 (but this only applies to LVM which you don't seem to use). Please copy&paste the output of
sudo blkid ls -lR /dev/disk/by-uuid grep -v '^#' /etc/fstab cat /etc/crypttab
Thanks!
