(These are perhaps too obvious, but I didn't see the questions or answers in the thread.) Can you reproduce it with a simple userspace cpu hog? (Two, really, one per cpu.) Can you reproduce it with the newer e1000? Can you reproduce it with git head? If the answer to the first one is yes, the last no, then bisect until you get a kernel that doesn't show the problem. Backport the fix, unless the fix happens to be CFS. However, I suspect that your userpace app is just starving the system from time to time. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
