Hello list,

I 've an embedded board with AMD Geode=E2=84=A2 LX 800 Chip. I'm runnin=
g Debian
Etch and Kernel 2.6.22.5. What I tried is to use dm-crypt /
cryptsetup-luks 1.0.5 with the Geode AES-Engine.

The Kernel Modul "geode_aes" is compiled and loaded successfully. The
problem is, that if the module is loaded and I try:
	cryptsetup -c aes -s 256 -h sha256 luksFormat /dev/hda2
after supplying the password I get the following error:

=46ailed to setup dm-crypt key mapping.
Check kernel for support for the aes-cbc-plain cipher spec and verify
that /dev/hda2 contains at least 258 sectors.
=46ailed to write to key storage.
Command failed.

If I remove the module (rmmod geode-aes) the cryptsetup works fine.
Any suggestions are very welcome.

Kind regards,
Markus
