Ethernet interface not found - eth0
 
Hi,

I booted an OS from live disk. The OS boots successfully but eth0 fails to start. I checked lspci , it outputs the exact ethernet card details :

(Broadcom Netextreme II BCM5716 Gigabyte ethernet)

Ifconfig -a returns only loop back interface 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 pointer will be helpful. Thanks for your time.

- Regards ,
Sethu

You have done the kernel thing, but have you done the obvious and fixed the WARNING message and placed files in the directory suggested?

Yeah I fixed the warning message, Now service network restart gives,

"Obtaining IP for lo [FAILED]

Bringing up eth0: Device eth0 does not seem to be present, delaying initialization [FAILED]"

But I dont know how to proceed debugging this problem :(

Just another thing, can you reseat and / or replace ethernet card?

post result of following after loading the driver
Code:

Driver might be failing at loading the firmware.
