Could you please re-perform the test applying the patch https://
git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6.git/commit/?
id=8e1fa89aa8bc2870009b4486644e4a58f2e2a4f5 ?

At least I am not able to reproduce that issue using the repro.c with the 
patch applied.

Thanks a lot.

Ciao
Stephan
