problem with Atheros 9280

[ltsampros]

Hello,

I have an Acer Ferrari One netbook (really, don't laugh on the Ferrari
badge), and it's wireless chipset is picked up by the atheros driver
correctly:

Feb 15 00:05:14  kernel: ath0: <Atheros 9280> mem 0xf0000000-0xf000ffff irq 19 at device 0.0 on pci9
Feb 15 00:05:14  kernel: ath0: [ITHREAD]
Feb 15 00:05:14  kernel: ath0: AR9280 mac 128.2 RF5133 phy 13.0

The above tests were done on 9-CURRENT with last update on Sun Feb 14
20:10:41 and built on Sun Feb 14 23:10:04 EET 2010 with a default
GENERIC kernel.

The configuration I have in rc.conf is the following:

wlans_ath0="wlan0"
ifconfig_wlan0="WPA DHCP"

and in wpasuppicant.conf:

network={
  ssid="philips"
  psk="super-secret-key"
}

Upon booting the machine the following entries are found and the wlan0
interface has not associated with the ssid:

Feb 15 20:21:03  kernel: ath0: bb hang detected (0x80)

Am I doing something wrong here? Upon request I can provide debugging
interface taken with:

hw.ath.debug=0xffffffff
hw.ath.hal.debug=0xffffffff

I hope I'm not doing something wrong. Thanks for the help.
