Cool! Can you share some code and register settings to enable this?

I think you should enable hostapd logging. That will log the MLME events.

You can look for missed beacon transmit events. That should tell you
if you're missing beacon transmission at all.

That's fine. That's what ath9k does with interrupts. :-)

There's a hw reset routine that gets called. You can just look for the
logging from that, or add a printk() yourself.
