ath9k doesn't work on Ubuntu hardy 64bit

hi,

I have a AR5418 wireless card within Macbook pro 3rd, i have been
using Madwifi(svn-3637) which is working great.
When linux kernel 2.6.27-rc5 getting released, I decided to git ath9k
a try, but unfortunately it doesn't working for me.

My system is Ubuntu hardy 64bit, here is the log from kernel.log:

The router is D-Link 624+A using WPA2 for authentication, the software
I'm using to management the network is wicd,
which has no problem with Madwifi.

If you need any detail information, feel free to contract me.

Thanks!
