This test was done on an OEL5.6 system, using the latest released RHEL kernel + 872 code.
Mike, we just discovered that our Cisco switch didn't have FlowControl enabled properly. It looks like it _should_ have autonegotiated to on, but may not have. We've manually forced it on and are running another test at the moment. I don't want to eat up too much of your time, so let me gather the new set of info from a new test fist. Then I'll attach the full logs.
