Hi All,
I have just built and booted with next-20160530 and my dmesg is full of
warnings from ath9k. Last kernel tested was v4.6 and there was no
problem with that.
The traces are like:

If it is a known problem then great.. else i can debug and see what the
problem is. There are only few patches added for GPIO, so should not be
a problem to find out what is causing the error.
