Network interfaces aren't picking up media on boot

Dear all,

I've moved my lovely server to the datacenter and now pulling my hair out while trying to understand why both of /dev/igb interfaces aren't picking up Ethernet connection on boot. Tested with both 10.3-REL and 11.0-REL.

When system is booted, running ifconfig | grep status over iKVM returns

Code:

status: no carrier
status: no carrier

However, after /etc/rc.d/netif restart && /etc/rc.d/routing restart it picks up the cable which is connected to one of the ports. Both interfaces are Intel I210AT integrated in the MB.

For the moment being, the only solution I see is to create a separate script in /etc/rc.d and restart netif/routing after boot is completed.

Could this be a problem specific to onboard interfaces?.. I was using this particular box in other environment without any similar problems on 10.0-REL.

Output from ifconfig when one of the interfaces is up:

Code:

UPDATE
On the other end it's connected into Dlink DES-1210-52
