[solved] kernel 2.6.27 - open LUKS encrypted root partition fails

Hi,

after updating to kernel 2.6.27 the passphrase for my LUKS encrypted root partition does not work anymore.

I get this error messages:

Enter LUKS passphrase:

device-mapper: table: 254:0 crypt: Error allocating crypto tfm
device-mapper: ioctl: error adding target to table
device-mapper: ioctl: device doesn't appear to be in the dev hash table.
Command failed: No key available with this passphrase.

Enter LUKS passphrase:

With a old (2.6.25) vanilla kernel it works.

any ideas?

EDIT
Solved.

The Problem was that I had this line in my mkinitcpio.conf to get rid of the padlock-error-message at boot.

#CRYPTO_MODULES="aes_i586 aes_generic sha256_generic"

With kernel 2.6.27 there are new / more modules needed to open the LUKS encryptet root partition.
So I removed the line from mkinitcpio.conf and deletet the padlock modules in /lib/modules/2.6.27-ARCH before regenarating the initrd image.

Thanks to GerBra for the tip.

CRYPTO_MODULES="aes-i586 xts" is still sufficient for me (aes-xts-plain, nothing blacklisted). Do you use cbc-essiv?

I'm not shure, but think ... yes.
