It didn't, but I talked to our mail server admin and now your mails should
reach me. :-)

After adding the debug outputs from your last patch, none of them was
displayed.
So I started adding some more outputs and doing a "line-by-line" debugging
and found out this (so far):

The freeze is the result of an invinite while-loop in the function
geode_ecb_encrypt()
(and maybe also in the geode_ecb_decrypt()).

The cause for this seems to be, that the op->src == op->dst whereby the
geode_aes_crypt() function does nothing at all,
and so the value of nbytes will never be changed.

Regards,
Martin
