I noticed the mail didn't get through to all lists, perhaps the
attachments were too large? (~135K)

You should use trace-cmd. Something like this:

trace-cmd record -e mac80211 -e cfg80211

And then send compressed trace.dat to Johannes. More info:

It did get through, at least here, but I didn't really see what part of
the change could have caused it; I'm not really familiar with ath9k_htc.

Do you think you could run trace-cmd to capture what's going on before
and after?

with ftrace.
