IEEE_80211_DEBUG is compiled into the kernel.
When I ran "wlandebug +scan", I got the following output:
net.wlan.0.debug: 0x0 => 0x200000
Then I ran "ifconfig wlan0 up" and then "ifconfig wlan0 scan".
The scan now took a few seconds, but still nothing shows up.
Then I took a look at dmesg -a which was now filled with a loop of the
following messages:
wlan0: ieee80211_start_scan_locked: active scan, duration 2147483647

The system kept on printing these messages until I rebooted this machine
back to Windows (in order to write this reply).
