>Description:
Hi, I have a problem on my FreeBSD system 9 RC3.
In order to find the problem with my wireless card Atheros (ar5413), I enabled the option in the kernel AH_DEBUG.
Unfortunately this option to reboot the system goes into kernel panic.
How can I fix this? 
>How-To-Repeat:
Then, the problem is the management of Atheros ar5413 wireless card.
(ath0: mem <Atheros 5413> 0xfdee0000 irq 16 at device 0xfdeeffff-4.0 on pci2
ath0: unable to attach hardware; HAL status 14
device_attach: ath0 attach returned 6) 

I enabled the option in the kernel AH_DEBUG.

This option to reboot the system goes into kernel panic
