I reported one of the duplicates that you've merged. I still see this warning running 2.6.31-19-server (x86_64).
I have a feeling this is related, in my case, to bittorrent traffic. This box is a NAS and SAN serving several diskless boxes over iSCSI, NFS and CIFS, and its gigabit NIC sees a LOT of traffic all the time. However I hadn't seen this warning for over a month. Last week I downloaded and seeded at decent speeds (10-20Mbps) several distro DVDs, and I got three of these warnings in three days, all implicating the 100Mbps NIC. It's all circumstantial, but could be a clue as to the root cause.
