Why are you sure that the hang is caused by the ar9170 driver? 

The vendor driver is called arusb_lnx, the new one ar9170usb

If you only use the packages from the above URL and haven't compile compat-wireless yourself,
chances are that you use the vendor driver. You may check the loaded module list:
	lsmod
and try to remove the module:
	rmmod arusb_lnx
before shutting down.
If this fails, try to close the corresponding netdev first:
	 ifconfig X down
with X = ath0 or wlan0 (see the output of "iwconfig").

Needing "--force" for rmmod is IMHO a bug in the driver.
