Thanks, Seth

I agree. That seems a more accurate statement. Without additional 
tracing (from e.g. wpa_supplicant?) it is hard to say what caused the 
disconnect.

I suspect the warning is caused because mac80211 flush callback is done 
after scanning on channels 12 and/or 13. I have a quick fix. The longer 
and preferred fix would be to cleanup channel.c and incorporate your 
regdom change. I plan to do that in separate patches.
