Ah - boo.
If I do, I'll need to know what precisely to do about it. What debug
info should I collect before rebooting?
Sure, OK so in ath9k's core.h we have a macro used to indicate what
type of debugging stuff gets print out. By default we only leave
enabled the fatal stuff.

#define DBG_DEFAULT (ATH_DBG_FATAL )

You want to add to this ATH_DBG_INTERRUPT as follows:

#define DBG_DEFAULT (ATH_DBG_FATAL | ATH_DBG_INTERRUPT)

Then since the issue seems to come up when you rmmod, simply try to
download do some large RXing or TXing or both and then rmmod. Capture
the output and send along.

Patches speak more than words, but yeah sorry, we should have
addressed this there. I've personally have just been busy with
tackling aggregation.
Which is far more important, I agree. It's annoying to get speeds
<802.11b on my pre-802.11n capable chipset and network. ;)
Yeah exactly, I hope the work we do will get in for 27. We'll see.
