I have recently built a new machine which has integrated Intel 82575EB NIC's. The RH EL5 installation was done using the 5.3 release, which supported the NIC cards and was performed using PXEBOOT and NFS install method. However, after the install was completed I proceeded to run full updates on the machine; which has brought it up to the latest 5.7 release with 2.6.18-274 kernel release. After these updates, the NIC card no longer works.
I can see that the igb kernel module is getting loaded in lsmod, however the NIC devices are not recognized. In dmesg I can see where it's loading the kernel module but it never recognized any NIC devices. I do see the devices in lspci output, but that's it.
This issue seems to be related to the previous bug 479436.
The kmod-igb-rhel5u5 package appears to have corrected my problem. I was able to install the RPM for this via a USB drive and now the NIC's are working again.
Please provide the output of lspci -nn and the output of dmesg when the NIC was not recognized by the system.
Please provide the information requested above.
