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

Apr 18 10:30:07 kernel: tg3: eth0: Link is down. Apr 18 10:30:10 kernel: tg3: eth0: Link is up at 1000 Mbps, full duplex. Apr 18 10:30:10 kernel: tg3: eth0: Flow control is off for TX and off for RX. Apr 18 10:30:24 kernel: tg3: eth0: Link is down.

etc...

   The interval for which it happens is about order of few minutes.The

kernel it is running now is 2.6.18-128.1.6.el5. Can anybody help.
