Ok, so it seems ntp hasn't really had a chance to settle down, its only
made a 10ppm adjustment so far. NTPd will stop corrections at ~
+/-500ppm, so you're not at that bound yet, where things would be really
broken.

If the affected kernel isn't resetting in the logs anymore, I'd be
interested in what the new ppm value is.
After 20 hours.. its still resetting.

So what's the "ntpdc -c kerninfo" output now?
