My bisect log showed the last "good" commit was
d5cdfacb35ed886271d1ccfffbded98d3447da17 and the first "bad"
53bc7aa08b48e5cd745f986731cc7dc24eef2a9f.

I tested those again and it seemed to confirm the initial finding. With
the "good" one I suspended/resumed at least twice, did rmmod ath9k at
least twice, and disabled wireless with NetworkManager, all without
incident. The "bad" one crashed the first time I tried rmmod ath9k.
