I am sad, unfortunately, freezes is not fully eliminated.
System freezes if powersave was switched off.
Also freezes (when powersave disabled) on kernel 3.14.2-1.
Please remove "Fixed in version linux/3.14-1 ~ with exp1" as the problem wasn't completely eliminated.
Workaround for me (works on kernel 3.14):
/etc/modprobe.d/ar9285.conf
options ath9k ps_enable=1
etc/rc.local
iw dev wlan0 set power_save on
