  And another one


  which I got while deconstructing wedges and partitions out of order. As
  Christoph pointed out, another null pointer issue; not sc though, which is
  checked in the caller dkstrategy().

This time the crash happens in sys/dev/dkwedge/dk.c, line 1200:

      nbp->b_dev = sc->sc_parent->dk_rawvp->v_rdev;

dk_rawvp is NULL.


  {Con, DE}structing the gpt setup was done with the scripts at
