Default DC7700 + intel = no gigabit speeds

Hi all,

I have a multiple HP DC7700s with integrated Intel ethernet adapters.
They work when the network cable is plugged into a 10/100 port on a
switch. They do not work when plugged into a 10/100/1000 port. I also
have DC7700s with integrated Broadcom chips (tg3 driver) and they work fine.

They all worked fine before the upgrade to F9.

From dmesg:
e1000e: Intel(R) PRO/1000 Network Driver - 0.2.0
e1000e: Copyright (c) 1999-2007 Intel Corporation.
eth0: (PCI Express:2.5GB/s:Width x1) 00:0f:fe:4a:68:37
eth0: Intel(R) PRO/1000 Network Connection
eth0: MAC: 4, PHY: 6, PBA No: 1002ff-0ff

Forcing 100 Mb operation with:
ethtool -s eth0 autoneg off speed 100 duplex full
makes everything work OK.

Forcing 1 Gb operation results in flaky or dead connections.

The auto-negotiated 1 Gb state is flaky/dead.

Now... I can force 100 Mb operation as a workaround, but does anyone
know what's causing this bug?
