I would say you are still missing some modules.

Kernel says this:
device-mapper: table: 252:1: crypt: Error allocating crypto tfm
device-mapper: ioctl: error adding target to table

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?

I both working 3.4 and non-working 3.6 situation is the same:

CONFIG_CRYPTO_CBC=y
CONFIG_CRYPTO_SHA256=m

Compare please:
grep CONFIG_CRYPTO /boot/config-3.4
grep CONFIG_CRYPTO /boot/config-3.6

One of the problem could be that your configuration misses something
like: CONFIG_CRYPTO_BLKCIPHER, CONFIG_CRYPTO_MANAGER, etc.. or some of
those could changed into modules and are not getting loaded..
