I would say you are still missing some modules.

It complains about aes-cbc-essiv:sha256.

It can be missing CBC od SHA256, but according the message I bet
you have no "cbc" block cipher mode module compiled.

Can you grep your final .config for CONFIG_CRYPTO_CBC and 
CONFIG_CRYPTO_SHA256 a paste it here?
