Network card keeps blinking when inserting the network cable.
I have a problem with one of my new systems: The network card starts blinking a lot when inserting the network cable, and when booting up CentOS, I do not get any link through that card.
The weird thing is that this does not allways happen, just for some combinations of network hardware.
* It works fine when attaching to my d-link router
* it works fine when attaching to one broadband modem (lyse.no)
* it fails when attaching to another broadband modem (lyse.no)
* It fails when using a crossed cable and attaching it to a d-link network card
Does anybody have an idea of what I can do to fix this problem?

it is possible, that your card is broken

As explained (poorly) in the original question, it works when put in certain hw combinations, and fails strangely when changing to some other combinations. The hardware is new, and I have multiple equal boxes set up. The all have the same strange error.
can you give the exact model of your network card?

It is an onboad network card.
The Motherboard is from ASUS (P5S-MX SE)
* CPU: LGA775 socket
* Chipset: Northbridge: SIS671FX, Southbridge: SIS968
* Lan: SIS 968 buit-in Gigabit MAC with external Attansic PHY
From "lspci" in CentOS i get the following information:
00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] 191 Gigabit Ethernet Adapter (rev 02)
00:04.0 0200: 1039:0191 (rev 02)
Does these details give enough information about the system?

Yepp.
From my experience SIS chipset is not very good one (it was, it is and it will be i think)
in your situation if it is impossible to return motherboard to the vendor try to use external NICs
btw, it is also possible, that your onboard cards will work perfectly under Windows XP(Check it?). In this case your dealing with poor drivers for linux only. Try to look for new drivers (or kernel for your OS)

From what I can see, there is more than one bug here, but the nic is not broken. that's for sure.
first. there is way too much garbage traffic on the network (about 7 Mbit/sek of garbage). This makes the network card blink.
Also the linux driver might be the problem. Auto negotiation might be the problem solve, I'll look into that next time.

But I only have this problem with this network card, but on multiple motherboards.
