I've seen reports like this with different cfg80211 modules running
than the one the driver was built for. Please show the output from:

modprobe -l ath5k
modprobe -l cfg80211
modprobe -l mac80211

Also you can run:

gdb net/wireless/cfg80211.ko

l *(wiphy_update_regulatory+0x98)

The above in gdb console should show you the culprit line.
