Ah - boo.

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.

Yeah exactly, I hope the work we do will get in for 27. We'll see.
