Looks like the vp is bogus (probably NULL).  Unfortunately you left the 
faut virtual address out, which is probably the most critical 
corroborating item.  It'd probably be < 0x100 in this case, if you're 
trying to get at the v_data element for struct vnode at 0.

Something's definitely wrong here; ufs would have crashed at the same 
point.
