    Hi all,

    I've got the following trying to debug
    FreeBSD current ( Mon Oct 27 16:34:36 CET 2003) on a serial terminal.
    Hardware:
    Supermicro x5da8
    dual xeon 2.66Ghz
    2GB ecc ddr ram
    Tekram 390u2we (system on a 36GB disc)
    promise sx6000 ( home on 6 WD1200JB (raid 5))
    Intel(R) PRO/1000 (on motherboard)
    Intel 82558 Pro/100

    I've disabled softupdates because of
    a panic("softdep_move_dependencies: need merge code");
    Could someone take a look at this?
