I wonder if it's related in any way to an error seen during login relating to 
an error in setting up /swap? In all recent installs, I've gotten cryptswap 
errors after boot during login. Just out of curiosity, do you have /swap 
available? E.g.,

    free -m

Any "missing" partitions? What do you see in fstab?
