I created a patch that (hopefully ;) disallows this. You can find it at : http://hobbes.bsd-dk.dk/~npp/kern_linker.patch I would appreciate if you have the time to test this to see if it aborts the loading correctly. I know it's not exactly the real fix but it should stop some panics. Could you also test if unloading the if_tap module panic's the system ? This should ofcourse be tested without my patch and preferably when a tap device is in use. > > voila, Arno Best regards, Nicolai Petri catpipe Systems ApS Ps.
