I am curious, somehow that patch makes a difference.

Guilhem, what do we actually compare: same kernel, just patched vs
unpached? Or these are 2 different kernels, and one of them was
patched.

What does 'uname -r'  say for the "with" and "without" kernels?

Did you compile both kernels yourself and the only difference between
them is the intel_idle patch?
