I did not look very closely at the provided information, but issues
between kernel- and userspace but not within kernelspace only could be
cache related. Did you try adding extra cache invalidate/flush

Another thing one has to beware of when using cryptodev is memory
alignment. Maybe your hardware does not like how the passed data is
aligned in userspace?
