Thanks, I'll test it during the week. 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. :)
