Hi all,
I'm facing a serious problem with the e100e kernel module for Intel 82574L gigabit nics on Centos 6.
The device eth0 suddenly stops working i.e. no more networking. When I do ifconfig from console I get
eth0 Link encap:Ethernet HWaddr 00:xx:xx:xx:xx:EA inet6 addr: fe80::225:90ff:fe50:8fea/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:37984 errors:54245436935850 dropped:9040906155975 overruns:0 frame:36163624623900 TX packets:20884 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4431149 (4.2 MiB) TX bytes:4628666 (4.4 MiB) Memory:fb900000-fb920000
Reported byte count and RX TX packet count is reasonable. Howerver the incredible large number of errors is not. Also they don't pile up but simply appear when the device stopped working.
In /var/log/messages I get:

The last line falsely reports the link to be 1000Mbit but it is actually 100Mbit. Same does ethtool.
Bringing down the interface with ifconfig eth0 down and then ifconfig eth0 up does not help. A reboot gets the interface back to normal. The problem returns after some minutes, hours or a day.
Any ideas? Regards .......Volker

Do you have either another port on the box, or can you swap in another NIC?

Probably related to this: http://bugs.centos.org/view.php?id=5034
This should be fixed in the 6.1 kernel and until that is released for centos you can install the Scientific Linux kernel package.

Not exactly the same as my problem, but likely related.
The kernel rpm of Scientific Linux 6.1 installed without problems. Let's see how this works out.

I had the same problem with an Intel Gigabit NIC and the e1000 module just last week on a fresh CentOS 6.0 install. Network will die for no explicable reason and fixable only by reboot.
Problem was solved by following one of the threads in the CentOS forum IIRC, using the elrepo kmod drivers.

I had pbms with my Intel 1000e too. Installed elrepo's kmod-e1000e and so far so good...

Also installed elrepo's e1000e from above url.
No problems so far.

Activating the CR repo and updating the kernel might also fix any issues with the e1000e driver (that did the trick for me).

Or create new ones, as happened to me

I have also had problems with an Intel Gbit nic in a Dell Optiplex 760 using the e1000 module. If it would come up it would come up at 100Mbit speed. Only unplugging the LAN cable en reinserting it in the switch would sometimes result in the proper 1Gb speed. After replacing the 3Com Gbit switch with a DLink Gbit switch things started to work ok.
As suggested, you could try out the e1000 kernel module form elrepo (if it works, good for you) but you may want to look into the switch too.

The fact that once you had changed to an other switch it had started to work points the blame to the 3Com switch. Funnily enough, about 10 years ago I would get the same kind of issues with 3Com network cards and switches talking to each other (on 100Mbit!). Disabling the auto-handshake and forcing the link to a particular speed would fix the problem.
Try forcing the link speed with ethtool or similar utilities.

Hmmm, we had a problem like that, but in our case, it was the NIC. If someone's already asked this - I didn't read the list over the weekend - ignore the request, but if not, while it's not working, what's the o/p of ethtool eth<whatever>

In our case, it was the driver. Google e1000e-1.6.2.tar.gz
