[Bug 131737] network device (nVidia MCP55, forcedeth) stops sending packets

Public bug reported:
Binary package hint: linux-source-2.6.15
The Sun Fire X2200 M2 (BIOS version S39_3B16, running Dapper and kernel
2.6.15-28-amd64-generic) has four built-in network interfaces. Two
network interfaces (eth0 and eth1) are nVidia MCP55 devices, and two
(eth2 and eth3) are Broadcom devices. eth0 and eth1 are connected to
Cisco switches, each on a different VLAN (although the interfaces don't
know that, as VLAN tagging is not in use). eth3 is unused by the OS (it
is active as the interface to the remote access system), and eth2 is
directly connected to another machine (via crossover cable). eth1 is
the primary interface, where most of the traffic flows.
eth0 and eth1 have been working well until a few weeks ago, when their
network connections were moved. They originally started out connected
to gigabit ports on a blade of a Cisco switch. The problem began when
they were moved to a 10/100 blade on the same switch. The switch ports
are hard-coded to 100MBps full-duplex, but the `ethtool` command reports
that the network interface is running at 100Mbps half-duplex. Also,
during certain circumstances, eth0 and eth1 can stop functioning. When
eth0 and eth1 stop working, no outgoing traffic is actually sent, and
incoming traffic can only be received on eth1. The problem always
affects both interfaces at the same time, never just eth0 or eth1,
always both eth0 and eth1. I have not experienced any problems (so far)
with eth2 and eth3 (although the OS doesn't use eth3).
I have found two ways at present to trigger the problem. The first
method is to flood the interface with a large amount of data. For
example, downloading many large files at once will eventually expose the
problem. Most recently, the problem appeared during a reinstallation of
Ubuntu: I had installed the OS from DVD, and was in the process of
upgrading/installing about 100 packages.
Another method is to attempt to change the network configuration. The
network devices, as I said, seem to run at 100MBps half-duplex, even
though the switch ports are set to run at 100MBps full-duplex. If I run
the command `ethtool -s eth1 autoneg off speed 100 duplex full` to force
the interface to 100MBps full-duplex, the connection on eth1 is lost.
Restarting autonegotiation does nothing.
This problem was noticed several weeks ago, when the machine's network
connections were switched from gigabit ports to 10/100 ports on the
Cisco switch. The diagnosis was temporarily delayed by a hard drive
failure (see Sun Online Support Center SR#65605769).
In an attempt to fix the problem, thinking that the Cisco blade may be
at fault, I have had the malfunctioning network interfaces moved to a
different 10/100 blade on our Cisco switch. The problem is still
present after the move; the network devices show the same problems
regardless of which 10/100 blade they are on. Unfortunately, all the
gigabit ports have been taken since the move, so I am unable to move
eth0 and eth1 back to gigabit ports to see if this fixes the problem.
To get the network interfaces working agin, besides moving network
connections, I have tried four different things. First, I tried
executing the command `/etc/init.d/networking restart`, which is
supposed to deactivate and then reactivate the network devices, but that
didn't work. I then tried executing the commands
`/etc/init.d/networking stop`, `rmmod forcedeth`, `modprobe forcedeth`,
and `/etc/init.d/networking start`. The commands should deactivate the
network devices, unload and then reload the driver for eth0 and eth1,
and then restart networking. This also didn't work. I eventually just
tried shutting down the machine (using the command `shutdown -h now`)
and restarting it, but that also did not work! Eventually, the only way
to get eth0 and eth1 working again was to shut down the system and
actually unplug it for approximately five minutes. That fixed the
problem temporarily.
Examining the /var/log/messages file, which records pretty much
everything reported to syslog, I found a number of messages relating to
eth0 and eth1:

[The above messages repeat every few minutes, as network packets attempt to go out]
[IMPORTANT NOTE: Although both eth0 and eth1 go down, I never see the above dumps for eth1, just eth0]
Here is how eth0 and eth1 are identified by the command `lspci -v` (run as root):
