This report sounds like the same issue: http://ehc.ac/p/e1000/bugs/378/ Oliver Wagner wrote the problem started to appear after updating from kernel 3.5 to 3.8.0.35 (new frag size code). I just noticed now he wrote he has two identical boxes: --------------------------------------------------- - Box with symptoms: Router/Firewall, packet forwarding between different VLANs on eth0 and eth1 - Box without symptoms: Fileserver, eth0/eth1 bonded (VLANs used, but no forwarding) --------------------------------------------------- So it looks like it's related to forwarding somehow, I've made the same experience IIRC.
