[ath9k-devel] Ath Country Code Issue

[Bill Jordan]

I have a system with 2 radios installed: an ath5k and an ath9k. The drivers
are all compiled into the kernel, so the cards are initialized very early. I
do not have udev running (yet); I'm doing things manually. When I run
"COUNTRY=US crda", I get an intersection of 00 and US instead of just US.

I've got some debug enabled:


PCI: enabling device 0000:00:01.0 (0340 -> 0342)
ath5k 0000:00:01.0: registered as 'phy0'

    (2457000 KHz - 2472000 KHz @ 15000 KHz), (300 mBi, 2000 mBm)
    (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 1700 mBm)
    (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
sh# iw reg get
country 98:
    (2402 - 2472 @ 40), (3, 20)
    (2457 - 2472 @ 15), (3, 20), PASSIVE-SCAN, NO-IBSS
    (5170 - 5250 @ 40), (3, 17), PASSIVE-SCAN, NO-IBSS
    (5735 - 5835 @ 40), (3, 20), PASSIVE-SCAN, NO-IBSS

Since both radios are US, shouldn't I end up with the full US setting
instead of an intersection?

If I remove one of the radios, I get the US domain settings.

Thank you for reporting this, this is a known bug, I will try to address soon,
unless someone beats me to it.
