NICs are found but fail to load the driver because of an error:
Jan 10 14:02:06 dstore kernel: bnx2x: QLogic 5771x/578xx 10/20-Gigabit Ethernet Driver bnx2x 1.712.30-0 (2014/02/10)
Jan 10 14:02:06 dstore kernel: bnx2x 0000:03:00.0: msix capability found
Jan 10 14:02:06 dstore kernel: bnx2x: PCI device error, probably due to fan failure, aborting
Jan 10 14:02:06 dstore kernel: bnx2x 0000:03:00.1: msix capability found
Jan 10 14:02:06 dstore kernel: bnx2x: PCI device error, probably due to fan failure, aborting
So this is a Linux or hardware issue, maybe look for a firmware update.
