Sorry, the above link does not fix it (I did double check that the kernel installed and booted correctly).
After an hour of the machine turned on battery, a similar panic happened (Fatal exception in interrupt w/ a call trace including ath and ieeee80211 functions). This was with the machine at idle (no major network traffic). Would be happy to continue trying other ideas (kdump, older kernels, automated bisecting, etc) if it is something that is quick to setup and try.
