I mentioned this in the bugzilla (229603 above), but we have at least
reproduced this here in our lab w.r.t e1000.  Some people were on
vacation this week so the issue didn't progress (regardless if this is
e1000 specific we will have some resources helping to report on this
next week).  So we're not sure if this is an e1000 problem yet.  More
soon, maybe I'll try to bisect back to some good bad branches, as the
problem is pretty quick to occur and didn't seem to be present in
2.6.20.
