I am running 2.6.20.2 on a whitebook laptop with a core 2 duo 1.86ghz 2gb of mem with an intel 945 shared memory graphics processor. I am currently running X with beryl have vncserver connected to my main system, which I am using to write this email, I am running also firefox and both of ingo test programs. I also am running a make -j4 on a kernel rebuild without having any pauses or any problem doing anything interactively.
So again what does this new scheduler fix?
