Subject: Deadlock in hacked 4.9.0-rc6+ kernel.

I ported forward my patch set to the 4.9 kernel, and I am seeing lockups fairly
often. As always, could be something I added locally, but in case someone sees
similar, then maybe I can reproduce it quicker and help track this down since my
test config uses many virtual stations and virtual APs.

And, if someone knows the magic trick to make dmesg output from lockdep
not be so split up, please let me know.
