>Description:
Nvidia MCP55 built in ethernet hangs the system immediately upon bringing up the interface via DHCP or with a static configuration via ifconfig nfe0 <args>.

relevant dmesg:

nfe0:  <NVIDIA nForce MCP55 Networking Adapter> port 0xe000-0xe007 mem 0xf2005000-0xf2005fff,0xf2006000-0xf20060ff,0xf2007000-0xf200700f irq 23 at device 8.0 on pci0
miibus0:  <MII bus> on nfe0

Motherboard model and version:  Gigabyte GA-M57SLI-S4 v2

I'd have given a debug dump but as soon as you bring the interface up the computer has to be hard reset.
>How-To-Repeat:
Simply configure and try to activate the NIC via DHCP or ifconfig.  The hard lock will occur every time.

 I have the same problem on 8.0-RC2/i386 but can workaround it with:
 
 hw.pci.mcfg=0
 hw.pci.enable_msix=0
 
 in /boot/loader.conf
 
 Maybe it's related to amd64/132372 - at least that's where I got the idea.

Close. Submitter has no longer access to the hardware. I think this 
issue might have been fixed long time ago.
