Attached is a dmesg with some sort of traceback that shows a failure
involving ath9k; I don't know that it's directly related to my problem,
since I don't get it all the time, but it is suspicious. I have another
dmesg from another boot that shows pretty much the same thing; I can
provide it if requested.

Here's what I figure is the important bit at the end:
