    Hi Francis,

    Thanks but I don't think that's the problem as i've
    seen it happen in lots of different machines with
    completely different hardware.. I'm currently
    battling a machine with 480W redundant power supplies.

    Is the Promise RAID any good? Is it controllable
    from FreeBSD ?

    Thanks,
    Adrian.
