Nothing exciting there either. Let's take a step back. The rfkill seems 
an issue, but I first would like to know if you can get connectivity. 
Does the 'ifconfig wlan0 up' complete at all and is it successful.

As you noticed during the up sequence there is a timeout. I would like 
to know what command that is. Could you run it again with debug=1546?
