hello,

I'm having a weird problem, eth0 does not start neither on bootup nor ifup...not even issuing /etc/init.d/networking restart...

i will show you some info just to check if you can help

Hope you can help!

What distro and version are you using? Can you post the contents of /etc/sysconfig/network-scripts/ifcfg-eth0 (if your system has that file?) Thanks.

First you should check why you load e1000e driver on eth4 which is not an intel card, possibly this creates some wired problems in device names.

Hi, thanks for the answer, following the content of my /etc/sysconfig/network-scripts/ifcfg-eth0

# Broadcom Corporation NetXtreme BCM5764M Gigabit Ethernet PCIe
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=no

I'm not sure why is this, i never changed the contents of modprobe.conf...so i've no idea how to check this...

Possibly the device order has changed for some reason(changing PCI slot of a card or replacing a card by another model). The first line of your ifcfg-eth0 states "Broadcom ....." which is not an e1000 card. This comment was added during installation,so it seems something has changed.

Check /etc/modprobe.conf and edit the file as required. Load the drivers for the devices as required. Recheck if network works.

Also, try this:

modprobe -r tg3
modprobe broadcom
modprobe tg3

Then: dmesg | grep eth

At the tail see if you receive this:

tg3: eth0: Link is down.
tg3: eth0: Link is up at 100 Mbps, full duplex.
tg3: eth0: Flow control is on for TX and on for RX.

Though eth0 might be ethX.

I have this:

/etc/init.d/network.sh restart
ifconfig eth0 up

You might have a different file.

BTW, You should first clear all the other junky configs. And heed what the gurus above said.

Finally, I like to try it out on a live CD.
