The second panic is caused in /sys/ufs/ffs/ffs_softdep.c:acquire_lock
(i.e. soft updates are on):
acquire_lock(lk)
struct lockit *lk;
{
pid_t holder;
if (lk->lkt_held !=3D -1) {
holder =3D lk->lkt_held;
FREE_LOCK(lk);
if (holder =3D=3D CURPROC->p_pid)
panic("softdep_lock: locking against myself");
else
panic("softdep_lock: lock held by %d", holder);
}
lk->lkt_spl =3D splbio();
(*) lk->lkt_held =3D CURPROC->p_pid;
lockcnt++;
}
The second panic happens at the line indicated (*) when CURPROC =3D=3D =
NULL (i.e. there is no current process)
