This will overwrite data on /dev/loop0 irrevocably.
Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase:
Command failed: Failed to setup dm-crypt key mapping.
Check kernel for support for the aes-cbc-essiv:sha256 cipher spec and verify that /dev/loop0 contains at least 133 sectors
server:~# modprobe aes
WARNING: Error inserting padlock_aes (/lib/modules/2.6.26-2-686/kernel/drivers/crypto/padlock-aes.ko): No such device
I even reinstalled the system, but it's always exactly the same.
Thanks a lot in advance!

had to do a "modprobe dm-mod" first, now it works
