I booted an OS from a live CD. The OS boots successfully but eth0 fails to start. I checked lspci, it outputs these Ethernet card details:

(Broadcom Netextreme II BCM5716 GBabyte ethernet)

ifconfig -a returns only the loopback interfaces lo and sit0. The output of dmesg | grep -I 'eth' is:

"Netfront : initializing network ethernet driver"

When I run service network restart I get:

"Obtaining IP for lo [FAILED]
WARNING: Deprecated config gile /etc/modprobe.conf , all config files belong into /etc/modprobe.d/
Device eth0 does not seem to be present, delaying initialization [FAILED]"

The output of MII-tool -v is:

No MII interface found.

I was also able to find the kernel module bnx2.ko. I did insmod and lsmod lists it. I am not sure what exactly is the issue or how to debug this problem. Any assistance or pointers will be helpful.

I believe that device also requires a separate PHY driver to be compiled. Look in the PHY section of the kernel config and select all of them as modules, just to be sure.

Can you please provide some more information regarding the PHY driver or how to verify ? I am not very familiar with this. – sethu Jul 19 '11 at 16:14
