There are many issues reported for system freezes regarding that kernel
module (ath9k), there is even a documented bug at the Linuxwireless site:
http://linuxwireless.org/en/users/Drivers/ath9k/bugs#Hangs_with_PCI_devices_and_SMP_systems
And even on Debian BTS:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=611946
I would try with an updated kernel.
