Hello Stefan,
thanks a lot for your effort, I've seen exactly what I expected (a
leaked recursion on 0xffffff002ae8dbd8 mutex (that I suspect is "TCP").
Since none of us can do on-line debugging in your machine, can you
please download that patch, apply it, recompile your kernel and doing
these tests again?:

It will give a good understanding of where the recursion happens and
where probabilly expected unrecursion fails.
Thanks,
Attilio
