[ale] Issue with eth0 appeared after setting up ethernet bonding

I'm going to go smack myself really hard now. It doesn't help that it was
already 4:30A Sunday when I first found this problem. I found the port that
NIC is connected to was set to 100FD. After setting it to Auto it, of
course, connected at 1000FD.
Thank you all for showing me the light.

I agree - it seems the other side is probably hard set so because you're
doing autonegotiate (which you have to for speed 1000) the other side is
probably setting it. Make sure the other side (switch presumably) is
set for speed 1000. Note that some older switches aren't capable of
this. If so you want to hard set the NIC to the slower speed rather
than letting it autonegotiate. We do that here on our RH AS 3 boxes
because the switches don't allow for 1000 (or didn't when we first
configured the servers).

Hmm. So eth0 is locking at 100 and half duplex. What is the status of
the cable and the other end of the cable that eth0 is carrying? Those
Intel nics are pretty good and very sensitive. Since they are being used
in a bonded pair, swap the cables and see if the error moves or
vanishes. Also type 0 bonding requires a switch that supports it and the
switch must be configured. Check the switch for being locked at
100/half. Since the nic is set for auto negotiate, it is being told by
something else to stop there.
