Uh, bp is 0 (NULL). Even if there were a member, you're not
going to find out its value, since there isn't one.
A couple of things you might want to try is to chase down the
vnode, instead, e.g.:
print *vp
(look for v_type)
print *(dn_p)vp->v_data
(if it's a devfs vnode)
print *((dn_p)vp->v_data)->linklist->name
(name of the device with the problem, if this is a devfs vp)
etc.
