A > bad cable seems odd given the speed is fine in one direction. It is possible to be a cabling issue. You could have a problem with its wiring for data in one direction (there's two pairs for each direction). Obviously you don't want to pull more cable through, but you can test with loose wire through the room between the machines. If that acts differently, try reterminating your other wire, one end at a time. I'd still suggest testing with another cable rather than just reterminating it. You eliminate the cable, itself, as a fault, that way. Swapping a NIC might be in order, too. -- (Currently running FC4, occasionally trying FC5.)
