igb0: Unable to map MSIX table

[macafee]

Today, I bought a new HP DL360P G8 pc server with a NC365T INTEL 82580chipset NIC and installed the FreeBSD8.3-Release. After the server restarted, I notice that the dmesg show following messeages.
igb0: <Intel(R) PRO/1000 Network Connection version - 2.3.1> mem 0xfbf80000-0xfbffffff,0xfbf70000-0xfbf73fff irq 30 at device 0.0 on pci4

The NIC was unable to map MSIX table? What' wrong? How to let the nic use the MSIX table?
