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...
