It's not so easy to reproduce, it will occur under high load (and disk IO) situations, e.g.when building the world (-j4). But not in every case, sometimes buildworld complete without a problem. If the system is in this state, it will react very very slow. System load is high (without a causing process) and it will often hang (during shutdown) when performing a reboot. I'll try your patch. -asc
