Can you use the latest backports release and post the kernel log when the
issue happens ?
https://www.kernel.org/pub/linux/kernel/projects/backports/2014/01/17/
The ath9k-debug config can be used in backports:
make defconfig-ath9k-debug && make && sudo make install
Load the driver with debugging enabled: modprobe athk debug=0x7cb
