But note that not every user reboots its computer everyday. I, for example, usually have it up for days. And when it comes to my laptop - weeks, as I just suspend it when I don't use it. Maybe the best way is to combine two patches. Also, you and others could also test these patches. It is not only my kernel that behaves strange. :) > Note: this patch change time related thing.
