It doesn't happen with Intel 3495 abg (wlan0) when 802.11n is turned off but will happen if 802.11n is active for other wifi adapters. It happens with RTL2800 bgn (wlan1), BCM43526 ac+gn (wlan2), Intel Centrino 6235 bgn (wlan3) and now with RTL 3072 bgn (wlan4).
Very aggravating, especially since since I don't know what CTRL-EVEN- SCAN-STARTED is and if I need on every minute instead of once a day. I might pick up an Atheros wifi adapter soon but I'll bet my favorite laptop sticker it'll have the same grief with 802.11n. And NO I'm not turning off 802.11n because I like seeing "Bit Rate:115.Mb/s" on my Conky display instead of "54 Mb/s". Could a kernel developer or network-manager programmer not give some advise to these many posts littering the netosphere please? Don't even get me started ranting about 802.11ac...

But it's spamming the syslog, making it very difficult to find any other thing there, and it's generating constant writes to disk, and an unnecessarily large syslog file.
