Re: Problems at encrypting a drive

As far as I remember essiv-mode for AES with CBC was not available
in the normal kernel for a long time. Actually I did not find
any mentioning of essiv-mode in a relatively current 2.6.17.6 
kernel konfiguration, and a grep for "aes-cbc-essiv" in the 2.6.17.6
kernel sources fails,  so it may be something that is not even in the 
latest kernel sources.

Try using plan AES with CBC as cipher.
