Strange thing... xx:xx:xx:04:85:aa IS the AP specified in my config 
file.  Looking at my log, I see lots of these message bursts, all 
separated by 60 sec (+/- a few sec):

RTM_NEWLINK: operstate=1 ifi_flags=0x11043 ([UP][RUNNING][LOWER_UP])
Wireless event: cmd=0x8c09 len=32
PMKID candidate wireless event: flags=0x0 index=0 bssid=xx:xx:xx:04:85:aa
RSN: PMKID candidate event - bssid=xx:xx:xx:04:85:aa index=0 preauth=0
RSN: Ignored PMKID candidate without preauth flag

Then, after the aforementioned ( http://pastebin.com/f491af16d ) 
sequence, my AP (xx:xx:xx:04:85:aa) gets added to the blacklist, and the 
wireless interface ends up appearing unassociated with an AP when I run 
iwconfig.

Is there any special meaning to seeing the event every 60 seconds, or is 
it just some value used in the driver?  I'm guessing the driver 
shouldn't be spamming wpa_supplicant with these messages, but is 
blacklisting the current AP the right behavior?

Is it even the driver that's spamming?
