panic at reboot - assertion: vp->v_lock.lk_exclusivecount == 1 in vgone_ interlocked

Commands used (script): inspired by vkernel(7):

vnconfig -cs labels vn0 FILE
fsck -y /dev/vn0a
mount /dev/vn0a /mnt
make installworld DESTDIR=/mnt
umount /mnt
vnconfig -u vn0

It might seem like panic occurs if I fiddle with /mnt while vn0a mounted: df; df /mnt
