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?
