I think there i som confusion here. Eithe both sides of the link need to be in auto-neg mode or both sides need to be forced to something like 100M/Full Duplex. This is by spec. If one side is forced and the other auto-neg unpredictable things can happen to the link.
Please try to force both sides to the link to 100/full and see if the problem goes away. I'm assuming that you are on a switch and not a hub, is this correct? And that it is a 10/100Mbps switch. Is this also corrct?
