We have two Dell servers which have an Intel I350 Gig 4 way network cards.  Both servers drop igb2 and igb3 after a short time.  igb0 and igb1 have so far been stable.  We are running the latest firmware from Dell and driver version - 2.3.4.
Any help or advice on fixing this would be much appreciated.
Nothing is logged apart from the interface going down with status: no carrier
Configure igb2 and/or igb3 and wait.
