I had the same thing happen with a 4.3R box with the if_tun kld.   (Machine
is in a remote location -- and according to the on-site help -- it rebooted
itself)

Subject: kldunload --> SYSTEM FREEZE


     Was experimenting with mods to the DRI modules on -stable, and half to
my surprise when I first tried a "kldunload mga.ko" (to then reload the new
version) my system locked hard.  I know what happened.  But I'm wondering,
what "should" happen.

     Would you say:

     a) Doh!  Well of "course" it's going to lock up stupid!  Don't do that!

     b) It really shouldn't lock up.  It should flat refuse to unload, but
        something is apparently broken.

     c) It should unload, but a pre-unload "cleanup hook" probably isn't
        implemented.
