Tested with 
git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git. 
(2.6.33, identical config als the previous 2.6.32)

Although up to 2.6.32 (2.6.32-3 in debian) I got still a recoverable 
OOPS (by removing mv_cesa), with the 2.6.33 cryptodev I get an 
unrecoverable OOPS where the all system hangs. Nasty.

This happens in exactly the same conditions as before (when the ipsec 
connection is estabilished through AES and SHA1 and some traffic tries 
that way. Last row before the crash:
[   41.799083] alg: No test for authenc(hmac(sha1),cbc(aes)) 
(authenc(mvhmac-sha1,mv-cbc-aes))


I'd get the trace via console (of little use really, I guess) or later 
try debug recompile to get some more clue (it will take some time though).
