Hi Herbert,
commit 73d3864a4823abda19ebc4387b6ddcbf416e3a77 leads to a
hanging modprobe aes_s390 process. If the process is
interrupted the following oops occurs:
------------[ cut here ]------------

That only happens if the aes_generic module isn't loaded. If
aes_generic is already present the aes_s390 loads without problems.
Any idea how to solve this? Is something missing in the fallback code
that uses aes_generic?
Cheers, Jan
