Thanks for the explanation here! My experience in this area is basically limited to the clock-related issues that I've sent your way recently, so I don't have deep wisdom to draw upon, but what you wrote here makes sense to me. If you can outline a testing procedure, we can test upcoming patches on Coffee Lake and Kaby Lake consumer laptops. Thanks, Daniel
