https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/1310058/comments/3 should have solved the problem, but no. After modifying /etc/cryptswap from:

cryptswap1 UUID=01234567-89ab-cdef-0123-456789abcdef /dev/urandom swap,cipher=aes-cbc-essiv:sha256

to

cryptswap1 UUID=01234567-89ab-cdef-0123-456789abcdef /dev/urandom swap,offset=8,cipher=aes-cbc-essiv:sha256

the problem persists. The same with the line:

cryptswap1 /dev/sdaX /dev/urandom swap,cipher=aes-cbc-essiv:sha256

after formating the swap partition with the old UUID:

sudo mkswap --label Ubuntu\ Swap --uuid 01234567-89ab-cdef-0123-456789abcdef /dev/sdaX

and rebooting the system. So I guess the problem is due to a race condition of the /etc/init.d/cryptdisks-early script. If I disable it the swap partition is mounted automatically on every reboot.
