e1000 Watchdog Messages

My problem is that the machine is not working normally. When using only eth0
(upper onboard NIC), the link actually goes down until I ifup/idown for that
iface. If I use only eth1 (the lower iface), I do not have any problems.

Basically, whenever eth0 is the sole active link it fails.

I see this message on just about every PE server I have that has an
Intel NIC.  The machine seems to work properly it just displays this
message.  Most on these machine are just using the eth0 NIC and the
other one is not used at all.
