Description Arjan van de Ven 2007-07-03 17:00:46 UTC 
Description of problem:

The tickless idle feature in the 2.6.21 kernel (as well as some of the related 
enhancements) saves a lot of power on laptops (upto 25%) as well as on 
servers. It's also very important for virtualization performance.

Having lower power usage and better virtualization performance is of high 
importance for your customers and as such this would be a really good feature 
to provide.

Looks like an itchy mouse-clicking finger...
