(I have a separate graph for resume.. but the graphing program does not show those things that take so short to resume that the font to print the name would be less than a pixel; can fix that) [fwiw I care more about resume speed than suspend speed, but obviously am happy if both get fixed... just resume tends to be much more user interesting, just like getting out of the idle loop matters more than getting into it] -- Arjan van de Ven Intel Open Source Technology Centre For development, discussion and tips for power savings, visit http://www.lesswatts.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
