No configuration found for eth0
 

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. Help is needed.

Didn't see anything particularly relevant here, but perhaps it will help:

It apears to me that you might have an unsupported network interface card.
Could you please post the out put from the lspci command.

example:
lspci

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.

Does a line like "eth0: Tigon3 [partno(BCM95702A20) rev 1002 PHY(5703)] (PCI:33MHz:32-bit) 10/100/1000Base-T Ethernet 00:0c:6e:2
f:16:a8" appear in dmesg| less?

Problem was with the version of the 2.6 kernel that loads with the IBM SLES EAL4 script. After running the script I upgraded the kernel to 2.6.4...244 and it works fine with the bcm5700 module. Thanks to all that replied.
