Hi Kim,

It turned out that the reason for this problem was actually a missing
crypto_aead_setauthsize() call. Setting authsize to 20 bytes
(i'm using aead with AES/SHA1) made things work.

However, we should add your patch to the talitos driver, as responding
to such an error with a Kernel OOPS isn't very polite :)

Thanks,

Sven.
