Hi everyone,
I have a Lenovo Thinkpad T420s with Intel core i7 @ 2.70GHz, 8GB RAM, Intel
SSD 160GB and iwn0: <Intel Centrino Ultimate-N 6300> mem
0xf4200000-0xf4201fff irq 17 at device 0.0 on pci3
Today, while connecting to different AP's, I noticed at one point that I
was not getting an IP although the wifi card was associated. Within
"wifimgr", I did a "Save and Reconnect" and then got a core dump.
Bellow, the bt:

One thing to keep in mind is that since I started using geli+ZFS (installed
with PC-BSD 9.1 cd), I always got "Cannot reset interface wlan0 - exit
status 1" with "wifimgr" whichever action i did (ex: reconect, rescan,
up/down,etc).
I would appreciate some help in debugging this.
