Thank you very much ! > Replace the Realtek network card (preferably with an Intel ! ) if you are using it. Try http://www.broadcom.com/support/ethernet_nic/driver-sla.php?driver=570x-Linux if using the BCM5705 interface. If this solves your problem, file a RFE in bugzlla.redhat.com because the current driver both in RHEL6 and in RHEL 5.6 is still based on version 1.108
