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

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

What should I be recording? The NetworkManager process? I'm unfamiliar
with ftrace.
