We have seen some hang issues using MSI-X on 82574 parts. Can you try reloading the driver the IntMode module parameter. IntMode=1 (you'll need a setting for each device in the system so two adapters would be IntMode=1,1) See if that changes the symptom you are seeing with this part. That setting will make sure the adapter uses MSI interrupts instead of MSI-X. Thanks, Carolyn Carolyn Wyborny Linux Development LAN Access Division Intel Corporation
