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
