Yes, of course I did. I clearly indicated that I did in my commit message
above. I just verified on a separate system as well. You had mentioned that
some of the standard NIST vectors that you obtained were failing on your system
as well, is something perhaps misconfigured in your kernel build? Mind you I
can't imagine what that would be, and if it were just my vectors that were
failing for you I could imagine I missed something that would work in my testing
but fail in yours, but if standard vectors are failing it seems something else
might be wrong
