Description of problem:

On my Dell Precision T1500, I have this NIC:

02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57780 Gigabit Ethernet PCIe (rev 01)

This doesn't work:

Jan  3 17:35:08 localhost kernel: tg3.c:v3.99 (April 20, 2009)
Jan  3 17:35:08 localhost kernel: tg3 0000:02:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
Jan  3 17:35:08 localhost kernel: tg3 0000:02:00.0: PME# disabled
Jan  3 17:35:08 localhost kernel: tg3 mdio bus: probed
Jan  3 17:35:08 localhost kernel: eth%d: No PHY devices
Jan  3 17:35:08 localhost kernel: tg3: Problem fetching invariants of chip, aborting.
Jan  3 17:35:08 localhost kernel: tg3 0000:02:00.0: PCI INT A disabled


Version-Release number of selected component (if applicable):

kernel-2.6.31.9-174.fc12.x86_64

How reproducible:

Every time.

A workaround is this:

rmmod tg3
modprobe broadcom
modprobe tg3

However, this also causes this (apparently harmless) oops:
