This happened while I was plugging in my laptop to the peripherals that are at my desk. I submitted another bug about a month ago that was related to the wifi hardware as well, this probably has something to do with the fact that my bios is set to disable the wireless card when it detects that the ethernet port has a cable in it.
I posed fix for this bug here: http://marc.info/?l=linux-wireless&m=136611945306948&w=2 Josh, please apply it.
Fixed on all branches. Thanks!
