eth1 not detecting link, despite NIC link light

hello
i have just added a new NIC to the server. when restarting the computer i see the link lights are on and green. When checking with the ifconfig the eth is shown but when checking with the ethtool it shows the link is off. i changed the cable the gbic but still the link is down.
the interface is connected P2P to another computer so the ip and route is not relevant, i just want to see the link on
i googled this problem and saw that i am not the only one who has it but there where no solutions. there was a very similar problem that was posted here but the solution was not entered.
i hope there is a software or connection problem here and not a NIC problem
thanks

Re: eth1 not detecting link, despite NIC link light

High end shit I haven't gotten to work with, but it is probably odd it only supports 10000baseT/Full and that the speed and duplex is unknown.

Have you tried different kernels? Live cd might be helpful. Maybe there is a bug in the current module?
