Angry Interface eth0 configuration not found


Recently installed SLES 9.3 and setup NIC card (Dell Broadcom) with a interface (eth0). All was working fine until....Ran the IBM SLES EAL4 script, which backs the Linux kernel from 2.6.5-7.244 to 2.6.xxx.111. After running the EAL script we have lost the eth0 configuration. Noticed that the directory in /sys/class/net/eth0 no longer exists. I cannot get the system to recognize the interface.

It is possible the driver was in the old kernel. It may not be in the new kernel you loaded.

OR did you load a module to support your NIC using modprobe ? Have a look as root using the command 'lsmod' to see if you have a module loaded to support your NIC. If not, you will need to load one.

If you need help figuring out what to load, as root run the command 'lspci' and post the results. I hope that will provide enough information to figure out what module to modprobe.

Then you will need to configure and activate the interface.

Ok...Ran lspci.

Results:
0000:0b:00.o Ethernet Controller: Broadcom Corporation Netxtreme BCM5752 Gigabit Ethernet PCI Express (rev 02)

Also noted that when I ran the command hwstatus 'hwcfg-bus-pci-0000:0b:00.o' that DRIVER='' .
Cat the file 'hwcfg-bus-pci-0000:0b:00.o' indicated the module was tg3. lsmod indicates that the tg3 is loaded.

Also: udevinfo -a -p /sys/class/net/ and the interfaces returned "couldnt get the "dev" file.
Furthermore: /sys/class/pci/drivers/tg3 is missing the 0000:0b:00.o directory.

Any further help is appreciated.

Your driver is loaded, and the device is seen on the PCI bus. All good.

The question for me is udev shoudl create a dev for the card. I don't know how to tell which entry in the /dev directory is for a ethernet card. Sorry I can't help any more than that. I hope someone who understands udev can chime in...
