Bug#611946: Freezes apparently caused by ath9k

[Tony Houghton <h@realh.co.uk>]

I've reassigned this bug to the latest unstable kernel because that's
affected too. I think the problem is caused by the ath9k driver because
any attempt to disable wireless or even disconnect usually causes
similar crashes.

I tried replacing network-manager with wicd but that crashed the system
when it connected instead of when disconnected.

2.6.32 from squeeze does not have this problem, but I've tried Ubuntu
Maverick which has kernel 2.6.35 and that exhibits similar symptoms. I
think I should report this upstream but I don't know the best way
to do that.
