Mark, I have not looked into this before today as I as been out of the office. I will take a look at this explanation and see if I agree with the assessment. There are some systems in beaker with ixgbe cards (and you can search by driver) so you may want to check some out and to try and reproduce this if you like. Can someone please post the full back-trace from the BUG halt? Created attachment 474009 [details]
