>Description:
I've just tried to upgrade to 7.1-RC2 and encountered the problem with an on-board gigabit RealTek. It doesn't work at all:

re0: <RealTek 8168/8168B/8168C/8168CP/8111B/8111C/8111CP PCIe Gigabit Ethernet> port 0xc000-0xc0ff mem 0xe2010000-0xe2010fff,0xe2000000-0xe200ffff irq 17 at device 0.0 on pci4
re0: Chip rev. 0x3c000000
re0: MAC rev. 0x00400000
re0: PHY write failed
re0: PHY write failed
re0: MII without any phy!
device_attach: re0 attach returned 6

I had to downgrade back to tag=RELENG_7_1 date=2008.12.16.00.00.00 to get the working system.

Here is pciconf -lv output for the NIC:

re0 at pci0:2:0:0: class=0x020000 card=0xe0001458 chip=0x816810ec rev=0x02 hdr=0x00
    vendor     = 'Realtek Semiconductor'
    device     = 'RTL8168/8111 PCI-E Gigabit Ethernet NIC'
    class      = network
    subclass   = ethernet

The motherboard is a GigaByte GA-G31M-S2L.

I'd expect this to get fixed before 7.1-RELEASE is out.
