>Description:
FreeBSD 9.0-RELEASE amd64 freezes on a xfx i780 motherboard nforce chipset when connecting 2 computers together directly. There was no kernel panic screen shown.
There is something wrong with the nfe0 driver when the link is connected and passing packets.

This PR report that has been closed references this exact problem in a different way.

http://www.freebsd.org/cgi/query-pr.cgi?pr=157132

I am attaching output of pciconf -lcbv, vmstat -i.
>How-To-Repeat:
With a xfx i780 motherboard nforce chipset,connect 2 computers manually.
assigning them ips and netmask manually.


>Fix:
NONE

State-Changed-Why:  
Would you post dmesg output related with nfe(4) and its PHY driver? 
Your vmstat output indicates it didn't generate any interrupts from 
ethernet controller so how about disabling MSI-X or MSI?

 I wonder how driver could fix silicon bug.  MSI/MSI-X with NVIDIA
 chipset is horribly broken in various ways. Making it work on these
 chipset may require lots of hacks by accessing undocumented
 registers as it did in Linux(NVIDIA also did not open data sheet).
 However, this also does not guarantee working MSI/MSI-X.  As you
 noted, FreeBSD lacks such hacks used in Linux so there could be
 cases that MSI/MSI-X does not work on FreeBSD even if Linux manages
 to make MSI/MSI-X work under certain conditions.
 
 The FreeBSD workaround you mentioned is not bad decision for a
 controller that is known to be broken in BIOS/chipset level.  If
 MCP55 chipset was broken I would have it black-listed in PCI layer.
 For your case it's still not clear whether the issue came from
 broken BIOS or PCI bridges.
 Show me the output of "kenv | grep smbios".

Hi yongari

The problem was solved by adding "hw.pci.enable_msix=0" and
"hw.pci.enable_msi=0" to "/boot/loader.conf".  There was no freeze and
computers were able to ping each other.

Moreover, disabling just MSI-X (hw.pci.enable_msix=0) caused "nfe0:
watchdog timeout (missed Tx interrupts) -- recovering" errors and
could not use ping. The computer did not freeze this time.

Lastly, disabling just MSI (hw.pci.enable_msi=0) caused the computer to
freeze on cable connection.

Robert
