Hi

Yum has just updated 5 of my Linux boxes running CentOS 4.3 to the 2.6.9-42 kernel.

All is well on four of the boxes, but on the fifth the network card (eth0) will not work. I've downgraded the kernel to the previous version and the network card works fine again.

I've tried removing and re-installing the new kernel, but the network card won't work with it.

The details of the card are as follows:

lspci:- 00:0e.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

/etc/modprobe.conf:- alias eth0 8139too

Any suggestions welcomed..

That card is to ubiquitous to have disappeared out of the kernel, I think. Undertake the info gathering and debug thing: check dmesg - is the card found? Check /var/log/messages for related messages. Do lsmod to see if module is loaded (I suspect not). See if you can manually do it (insmod or modprobe the driver, try to manually config card, ...). That may give your answer. Or it may give at least some clue. Look in the modules directory to see if the module exists?

Armed with that, someone might be able to help.

Thanks

Clive

I'd offer more, but the one I'm running right now has the gigabit Realtek, not the 10/100.
