This looks a LOT like bug 558809, but it doesn't appear to me that the 82541 could be a problem too since it doesn't do packet-split. That is unfortunate.
This is a year old and it seems like problems that often happen on one system are due to a BIOS/firmware problem on that system. I'm going to close this as NOTABUG.
