Hmmm, should kern.polling.suspect & kern.polling.lost_polls keep incrementing? Mine increment steadily. If you set kern.polling.enable=1 - they stay at zero - send a burst of traffic, and they keep incrementing steadily after that (about 20 or so a second). Even if there's no traffic at all... I don't seem to encounter any packet loss because of it... [This is with DEVICE_POLLING and HZ=1000 set in the Kernel config] - using 2 x em [Intel Pro-1000TX Cards both @ 100Mbit/FDX]. -Kp
