DWL-G520 problem in FreeBSD 5.4

[Luis Sandoval]

Hi,
I'm trying to setup my Card Dwl-G520 in FreeBSD 5.4 and  not working.

I try:

kldload if_ath.ko

and dmesg output is:

ath0: <Atheros 5212> mem 0xff7f0000-0xff7fffff irq 21 at device 0.0 on pci6
ath0: unable to attach hardware; HAL status 13
device_attach: ath0 attach returned 6

error:
HAL status 13=Hardware revision not supported

strange, my card work in Linux (driver madwifi) perfectly.

Any idea?

thanks,

Luis
