Hi,
  Thanks for looking into this.

It definitely doesn't. I've tried with only the onboard device
and no other NIC device (r8169 or not) installed and its the same
problem.

See attached text file. I'm not sure why I get so many interface up
messages. This is for the two NIC cards. I can pull them out and go back
to the onboard one if you like.

I don't see that transmit queue timeout message that often. It looks
like it might happen once per boot and then giveup.

I set it at 65535 but it didn't seem to make much difference.

If I:
  * rmmod r8169
  * modprobe r8169 debug=1
  * ifconfig eth0 ....
  * ethtool -s eth0 msglvl 65535
  * ping -I eth0 ...
I get the following:
