Comment 42 for bug 1542944

Thanks Pilot6 for solving this.

After fixing bluetooth, I suffered from the so-called bluetooth coexistence issue. That is wifi stopped working whenever bluetooth was in use. Does this affects you as well damien? The solution is mentioned here:
https://wireless.wiki.kernel.org/en/users/drivers/ath9k/btcoex

In my case, I had to
sudo modprobe -r ath9k
sudo modprobe ath9k btcoex_enable=1

This is essentially a bug too unless done automatically by the system. Can it be fixed through here or should I report it somewhere else?
