I sent this to Don via email while waiting for my confirmation email to arrive. Figured it would also be worth-while posting on the list as others might have similar issues and are scratching their heads...
When you have large swings in your offset from one way to the other, it usually points to a misconfiguration in some "power savings" feature, either in the BIOS or in the OS... Either way, to achieve maximum time stability it's usually preferred to disable anything that will throttle the CPU clock speed. To test and see if that is the cause of NTP misbehaving, simply go into your BIOS and disable any power saving features (i.e. SpeedStep, Cool&Quiet, etc, etc...) If NTP runs stable after that, then you can slowly re-enable features one at a time and see exactly what is causing the issue. Another tip is to append "maxpoll 9" to your ntp "server" lines, that will set the upper polling limit to 512 seconds instead of the usual 1024s... i.e.: server 192.168.1.25 iburst maxpoll 9 That can help to get NTP synced faster & better typically reducing your rootdispersion some.
