Try yanking your NIC and see if the problems persist?

Ath9k has it's issues, but it's surely not the only thing that
can lock up a system..and it usually spews all sorts of warnings/errors
before it does lock up a system.

And, recently it's been much more stable..so try a 2.6.39 kernel perhaps?

Thanks,
