System Encryption with LUKS

I'm trying to encrypt my /root partition, however I keep getting an odd error message and I can't seem to figure out why. I'll enter:

# cryptsetup -c aes-plain -y -s 256 luksFormat /dev/sda2

And I'll get a message telling me:

Command failed: Failed to setup dm-crypt key mapping.
Check kernal for support for the aes-plain cipher spec and verify that /dev/sda2 contains at least 258 sectors

Kernal version is 2.6.30. Anyone know how to fix this?
