Not ringing any bells, but if this timeout is happening, you should also be seeing some igb "TX Hang" warnings. Usually this warning happens when some packet is stuck (for whatever reason) in the transmission queue.
Can you share more details about what you are running? specially the kind of configuration (if any) you are doing to the controller.
Cheers, -- Vinicius
