It appears that the hunting is rather too good. Both "no buffer space
available" and "Can't assign requested address" have numerous possible
sources. Using wpa_cli as a logger distinct from the console output
is likely more productive. 

My first thought was to use something like
wpa_cli > wpa_cli.log &
on the serial console, but backgrounding the job seems to suspend wpa_cli.

Strangely, starting 
wpa_cli > wpa_ci.log
in the foreground, suspending it and then putting it in the background
with bg lets it keep running. That's aberrant. 

I'll let it run overnight.

Thanks for writing!
