In my defense, the patch documentation didn't say it doesn't work with my hardware, nor that it hangs the chipset :) and the promised 1.3w surelly looked nice. So, are there any benefits of ASPM if I have it in the kernel but it's set to default? I got the impression that "default" means not much power savings? -- Damjan Georgievski Free Software Macedonia -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
