Error with Atheros chipset.

Hi Guys.

I've recompiled -CURRENT with support for atheros cards.
I have two cards, one PCI(desktop) and one PCMCIA(laptop). Both are Proxim 11a/b/g combo cards with AR5212 chips.
The cards are recognized fine. 
pciconf -l -vv shows:

ath0_at_pci2:4:0:  class=0x020000 card=0x0a6014b7 chip=0x0013168c rev=0x01 hdr=0x00
    vendor   = 'Atheros Communications Inc.'
    class    = network
    subclass = ethernet

dmesg shows:
ath0: <Atheros 5212> mem 0x40000000-0x4000ffff irq 5 at device 4.0 on pci2
ath0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
ath0: 802.11 address: 00:20:a6:4c:ef:62

I've tried every possible example combo from man ath(4), i.e:

ifconfig ath0 inet 192.168.0.1 netmask 0xffffff00 ssid my_net mode 11a mediaopt adhoc

to create adhoc network.

The problems start when I try to configure them with ifconfig.

Every attempt result in following errors and lack of communication between them:
ar5212AniGetCurrentState: Out of space in ANI table for channel 5785/0x140!
ar5212AniGetCurrentState: Out of space in ANI table for channel 5805/0x140!
ar5212AniGetCurrentState: Out of space in ANI table for channel 5825/0x140!
ar5212AniGetCurrentState: Out of space in ANI table for channel 5785/0x140!
ar5212AniGetCurrentState: Out of space in ANI table for channel 5805/0x140!

etc etc.

Any idea how to fix that and how to make the cards work? A simple ping would make my day :)

Greets,
