Folks, I have a Compaq, witha ThunderLan NIC, connected to a Cisco Switch. Straight connection, no hub or anything in between. On the Cisco, the monitor shows a high degree of Runts. Over a 1 min period, with the link running 50% util over 100Mbps half-duples, I see about 10 collisions, and a few hundred runts, plus a dozen giants. [...]
We had a similar problem with Intel Etherexpress Pro / Summit 48i.After some tweaking the link is OK ONLY when both sides auto-negotiate the speed. Fixing a given speed on one side and auto-negotiation on the other slowed down the connection speed by about 80% under "heavy" load.
I'd suggest trying to play with speeds / Duplex / Auto-negotiation settings. You may want to have a look at tcpdump too... Maybe you have an ARP problem ? Good Luck Olivier
