I sold that laptop last week, beside this wakeup problem it had kernel panics
half of the boots after changing wlan ap from d-link to zyxel. The last kernel

knoppix v6.7.1 shows a high wakeup rate, too. But that is kernel 3.0, finnix

It's great that kernel bugzilla is back.
can you please verify if the problem still exists in the latest upstream

John, perhaps this wasn't too clear but in the very first comment I stated that

Depending on load.
As for at5k

Maybe I'm missing it, but it seems like you are just showing some numbers with
no clear indication of either what you think the numbers should be or why you
think ath5k is at faul

I'm a bit confused, can you characterize the # of wakeups with/without ath5k?
You seem to say unloading it drops the number of wakeups, but that it doesn't
have a lot of interrupts?
