Ok, but that means you _can_ get messages, it would help a lot if you could put a few printks into the set_disassoc function before/after each other function call, so we know where exactly it hangs. Pretty much all of them could possibly hang if there is some sort of locking error happening or anything relies on userspace to be running... johannes
