I found a reliable way to reproduce the firmware crash. I connect to my
home network, then do 'sudo service connman stop' and boom, the firmware
has crashed. I suspect it has nothing to do with connman, most likely a
simple disconnect will suffice but I didn't bother to test that.

I did a git bisect and it points to Aloka's recent commit. Luckily the
commit is only in ath-next so far and not in any release. My plan is to
submit a revert by tomorrow so that we get this fixed before pulling
ath-next into wireless-next.
