The autonegotiation probably fails on one end. You are having a system
where one guy is in FD and another one is in HD. If the errors occur due
to collisions, this is reason. See from the hub console whether it is
in HD mode. 82558 should be quite good in autonegotiation, so I would
first suspect the linksys hub.
