Realtek chips are junk with unpredictable reliability, especially under heavy load. I have had several problems with various versions of the 81xx chips. When I tossed the cards in the garbage and switched to Intel-based NICs, all the problems went away. Every time I build systems with Realtek network chips on the motherboard, I disable them in the BIOS and add Intel NICs instead. YMMV, but please consider ditching Realtek altogether.

[CentOS] Failing Network card
Everyone, Most of the time I am over my head in trying to troubleshoot problems. However, after reading manuals, man pages, and getting advice from this list I have been able to work my way through difficulties, and at the end, I usually have a better understanding of what 'is going on'. I can only hope this method will work on this problem too. I have been chasing a problem with a pci-e TrendNet(TEG-ECTX) gigabit card. After adding the card to a machine with a new Centos 6.2 install and naming it 'eth4' it works well for 6 to 12 hours and then fails. The failure is characterized by dropping its connection speed from 1000 to 100 while not allowing any data to flow in or out. When this happens a shutdown and reboot does not solve the problem, but shutting down and then removing the power does solve the problem. I wrote a perl script that uses the eth4 interface by pinging another machine every 60 seconds to try to figure out the relationship of the message log entries with the time of failure, and I think there is a corelation of the failure of eth4 to function with the below entry. Unfortunately, I am way over my head on this one. If any of you can help I would surely appreciate your thoughts. Some additional information that may be useful. The TrendNet card is the second TrendNet card I have used. The first card had the same symptoms, and I deduced the card was bad, and purchased another one. The symptoms are the same with the second card. Before I purchase a third card from a different manufacturer I thought I would post this to see what some of you think. This is the first pci-e card I have used; are there problems with the pci-e interfaces as opposed to pci? Do you think the motherboard could be the problem, and moving eth4 to a different slot on the motherboard would be worthwhile. Any ideas ??? Greg Ennis P.S. Here is the appropriate log entry in the /var/log/message file.

After this problem surfaced with the failure of the eth4 card (internal network), I created a gateway out of one of the other machines that is working without incident. I did purchase both TrendNet Cards from Fry's. Fry's was good about taking the first one back without question, but now that the second one has failed, I thought it best to look deeper. I don't have the previous card's MAC address, but my first thought was that this was a bad card too. Both the first and second cards did not appear to have any damage on the boxes or the card itself. Before I tried to get a third card from a different manufacturer I wanted to post things here to see if there was an obvious problem I am missing. Thanks for your help!!! Greg ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos If you are having to fully 'cold boot' the system before it will work again I can't help but wonder if it is a conflict between special motherboard functions/settings and the card.

Do you have a different machine/motherboard around where it wouldn't be hard to set up this testing? Maybe Googling a bit on motherboard model and eth card model might give a helpful return?

I had this machine set to be a gateway for the rest of the internal machines. I only have two nics on this system, eth0 and eth4. The reason it is labeled eth4 is related to some installation problems I had during the installation of the pci-e card. Once I got eth4 to work, I have been too lazy to go back and modify things to relabel it as eth1. Now that it is failing, I am glad I left it alone.

have you deleted all the information from udev of the old card you
pulled out.
Could be an issue, not sure, if you are using the same slot ?
Sometimes you get bad batches though and one failure can mean many more too.
if both cards had the same issue, then I doubt udev or any of that is at
fault.
Having to unplug power to the machine is odd, but would support a bad
card idea.
Try instead of pulling plug, rebooting but unplugging network cable
first, see if that has an effect.
I would just return it and get a different type of card...or try an
extra one you have lying around.
All I know is with computers is come down to two things
1) its broke, return it
2) its something really silly, usually one misconfiguration or error,
something simple but overlooked.
