I tried with some kernels (hey, vmware had serial ports?) For whatever reason, the timecounting is not accurate. As you can see, the time difference between "WP bit" and the calibration thing is less than half a second inside the guest, but on the host, the delay is several seconds. The Capture Movie feature gets it right http://jengelh.hopto.org/f/2618delay.avi One can see that it pauses before calibration (already mentioned that) and once again after NET: ... during IP init!?
