Atheros 5424/2424 problem with scan

[Bruce Anthony Grobler]

Hi

Just got my wireless card recognised (Atheros 5424/2424 ), 

dmesg:

> ath0: <Atheros 5424/2424> mem 0xf6000000-0xf600ffff irq 19 at device 0.0 on pci3
> ath0: [ITHREAD]
> ath0: WARNING: using obsoleted if_watchdog interface
> ath0: Ethernet address: 00:1f:e1:6a:98:4f
> ath0: mac 14.2 phy 7.0 radio 10.2
> 

though when I do a ifconfig ath0 up scan it hangs, 

here are my configs/versions:

from my kernel config:
