Public bug reported:

I have 3 wireless adapters.  One is built in and present on boot
(ath5k).  This adapter respects the REGDOMAIN= setting in
/etc/default/crda.  I then plug in a USB adapter, an Alpha with a
RTL8187 chipset (AWUS036H).  REGDOMAIN is still respected.  Finally, I
plug in another USB adapert, another Alpha but this one with a AR9271
chipset (AWUS036NHA).  This adapter has the regulatory domain set in the
EEPROM, which for some reason is set to GB. The problem is that when
plugged in, the regulatory domain for all of my adapters are now being
set to GB.  To correct the problem I have to do a "iw reg set xx" and
then "iwconfig yyy txpower=z" to get the first two adapters back to
their proper power levels.

Plugging in that final adapter should not effect the settings for first
two!

The key lines in dmesg read:

ath: EEPROM regdomain: 0x833a
ath: EEPROM indicates we should expect a country code
ath: doing EEPROM country->regdmn map search
ath: country maps to regdmn code: 0x37
ath: Country alpha2 being used: GB
ath: Regpair used: 0x37

after which cfg80211 does the reset.
