} The info intr seems lost.  Try using wicontrol to squeeze more

} works for you.

Thanks for sticking with me :)  I recompiled the kernel and enabled polling, then did as
you suggested.  The results are below.  One thing that stands out is that in the first
``wicontrol'', the "Current BSSID" does match the MAC addr of my base station.  In the
subsequent wicontrol (after I did some ifconfig stuff to tell it to go find any station)
that value reverted to 44:44:44....

The debug output and pattern is identical with polling on as when using interrupts. 
When I ifconfig the interface up, I get no messages.  When I ifconfig it down, I get the 

wi_newstate INIT -> INIT
ieee80211_newstate: INIT -> INIT

lines.  I can repeat that as often as desired; ifconfig up => no messages ifconfig up then 
later down => the INIT -> INIT pair above.


Here's a transcript, edited to better space the lines out.  The AP is operating at this point
with WEP turned off, access control turned off, and is broadcasting its SSID.

laptop# sysctl debug.ieee80211=2
debug.ieee80211: 0 -> 2

laptop# sysctl hw.wi.debug=2
hw.wi.debug: 0 -> 2

kern.polling.enable: 0 -> 2
