Dear All,

             I am having a HP xw4400 with following ethernet controller 
as reported by lspci

Broadcom Corporation NetXtreme BCM5755 Gigabit Ethernet PCI Express (rev 02)

             This machine was running CentOS 5.2 without any problem. After 
updating the machine with yum update on 8 April, after which it is showing 
to be CentOS 5.3, this machine stops communicating intermittantly and I 
see the following message correspondingly in /var/log/messages
