Hm, thats not much information. So here some question to enrich it a little 
bit (otherwise I have no idea were the problem might be as I could not 
reproduce it yet).

How did you connect? Using serial console or using lan (from output I would 
guess serial console).

Does the hang always happen?

Can you reproduce the problem with the version in linux-2.6.36-rc3 or 
maint/next of the batman-adv git repository? Can you reproduce the problem by 
doing the necessary insmode/iw/batctl/rmmod steps by hand (aka no 
configuration using /etc, but manually)? What where your calls? Which call 
made it hang? Can you drop parts of you iw/batctl calls and the hang still 
occurs?

Can you add printks in hard-interface.c around the call of 
hardif_remove_interface inside hard_if_event to check if it stops inside that 
function and if it does then please try to add more printks inside of 
hardif_remove_interface and hardif_disable_interface.

thanks,
	Sven
