Hi,

So either the upstream patch is broken, or the 4.1 backport is wrong/missing
dependency/missing fix.

Any chance you could try 4.5-rc3 and see if that works for you? That'll narrow
it down a lot.

4.5-rc3 works for me.

Linux-4.4.0 works, too.

Herbert,

Is there a dependency I missed in 4.1? I don't really see anything that
could have gone wrong there.

Or maybe Thomas can run a bisect ? Thomas, do you feel comfortable with
doing this ? There are a few patches between 4.1.17 and 4.1.18, in 8
steps it should be done, and only 4 if you limit yourself to the crypto
directory. Stable versions are fast at bisecting because each patch
touches a very isolated area so only the first build takes a bit of
time but the other ones are often pretty fast. Finding the faulty
patch can help spotting if something is wrong in its backport.
