There are two uses for hash - one is for userspace (LUKS and passphrase
hashing in plain mode) and the second is used in ESSIV in kernel.
The best is paste error messages (add --debug) so it is clear what is
the exact problem.
If it is about kernel part, dmcrypt is here simple user of cryptoAPI,
so it depends on the module autoloading.
(Better ask on kernel crypto list http://vger.kernel.org/vger-lists.html#linux-crypto )
