I'm trying to suggest eliminating this driver & possible interaction with Xen network changes as a cause. If you can find a different type of NIC to plug in and use, or even try and change all of the params for the tg3 with
ethtool, it'll help.


Thank you for the assistance. Which parameters do you suggest changing?
TSO/flow control off?

Yep, anything.

Ok, "ethtool -K eth0 rx off tx off sg off tso off" should have turned it all off.

I think I confirmed the NIC is not the source of the problem. A few of my servers have e100/tulip NIC's due to a bug with the chipset of the on-board TG3 cards firmware and TSO. These servers that use the e100/tulip drivers also experience the ipt_do_table bug.
