    That's less of a problem as boards have started to conform better,
    but I definitely checked it - full-duplex worked fine (I could push
    over 15 MBits aggregate).  My packet loss occured with both half and
    full duplex.

    I finally tracked it down.  The loss is occuring in the link between
    two of my switches.  The link goes across my apartment - about 60 feet of
    Cat-5 cable.  That should be well within spec (you are supposed to be
    able to do 100 meters) but it causes packet loss.  The switches 
    autonegotiate full-duplex for the link (and I verified that it's actually
    running at full duplex), but that's where the packet loss occurs.  Very
    weird.

    I was finally able to fix it by dropping in a 10BaseT hub to force the
    switches to negotiate 10BaseT across the link.

    Maybe my cable is damaged or something.  I'll run a second cable to see
    if that's the problem or whether.

    The second switch is a LinkSys.  I have a D-Link near my servers and a
    LinkSys near my workstation.
