Cause of this bug is - Intel GigE goes into some confused state upon
"suspend" which affects Ethernet switching.

Effects of a cross-over cable or a Ethernet hub are the same. Packets
reach every port blindly (no switching).

There is a configuration option in Cisco IOS to make a switch
behave like hub when there is no matching ARP entry or during the
spanning-tree table-rebuild phase. 


I think Ben should take a look at rmmod issue. I have noticed this
problem with Redhat's default kernel (without elan) too.

| 2) Why would packet drops to a halted node be 90% and not 100%?
| 
| 3) Why did the power control/hatl problem not occur on our test

| 4) Why did "rmmod e1000" not occur on our test cluster??
