Description peter 2013-10-05 09:40:00 UTC
Kernel crashed when I try to create a second wlan device. It happens both when I use a wlandev that is already assigned to another wlanX and when i use another wlandev.

How-To-Repeat: # ifconfig wlan0 create wlandev ath0
# ifconfig wlan1 create wlandev ath0

OR

# ifconfig wlan0 create wlandev ath0
# ifconfig wlan1 create wlandev ath1
