FWIW, I had the same configuration (with switches instead of hubs)
and were getting the same errors in a couple of boxes.

When I certified the patch cords of the top two machines appearing
in the logs with a WireScope 155 I found one of them bad. After
replacing both of them, I've seen no more messages like those.

At first I was bitching about the cheap cards or the driver but hey,
it was the cable. What stroke me is that even with an expensive
cable-testing device one of the cables was 'good'!

Regards.
