Still seeing this BUG with -rc5, that I originally reported here:
http://marc.info/?l=linux-crypto-vger&m=134653220530264&w=2

Can you try blacklisting/not loading sha1_ssse3 and aesni_intel
to see which one of them is causing this crash? Of course if you
can still reproduce this without loading either of them that would
also be interesting to know.

It happens with the C variants of SHA1 and AES, too. You can easily
trigger the bug with Steffen's crconf[1]:

$ crconf add alg "authenc(hmac(sha1-generic),cbc(aes-generic))" type 3

So the problem is likely not related to sha1-ssse3.ko or aesni-intel.ko.
