Intel Pro network card problems on FC3


Hello.

I have a bridge named "br0" on 2 Intel Pro network cards with interfaces eth0 and eth1.

and I constantly getting one of link down for some seconds with following errors:


kernel: e100: eth1: e100_watchdog: link up, 100Mbps, full-duplex
kernel: br0: port 2(eth1) entering learning state
kernel: br0: topology change detected, propagating
kernel: br0: port 2(eth1) entering forwarding state
kernel: e100: eth1: e100_watchdog: link down
kernel: br0: port 2(eth1) entering disabled state
kernel: e100: eth1: e100_watchdog: link up, 100Mbps, full-duplex
kernel: br0: port 2(eth1) entering learning state
kernel: e100: eth1: e100_watchdog: link down
kernel: br0: port 2(eth1) entering disabled state
kernel: e100: eth1: e100_watchdog: link up, 100Mbps, full-duplex


What does this mean ? Why the link goes down ?

Please help. Thanks in advance!

According to the link in my signature for Fedora & Red Hat device driver and kernel bugs, certain kernels from Red Hat in combination with the eepro driver might have a problem.

So...

What kernel are you using? uname -a

What Intel driver is installed? lsmod

What IRQ's is the system using? cat /proc/interrupts

What does this say? lspci --vv

Are you trying to team those NIC's?

If so, did you download the driver from Teaming package from Intel.com?

What do you mean by "team those NIC's"?

I tried to change the driver from e100 to eepro100
but this didn't help.

And only one card has such problems - eth1 , eth0 working fine.
This happenned after upgrading linux from RH9 to FC3.
There wasn't any problems with those NIC's on old system....

What can you suggest ? I don't know what to do...
