Phoronix: A Proper Solution To The Linux ASPM Problem
At long last, it looks like there is an adequate solution to the Active State Power Management (ASPM) problem in the Linux kernel , a.k.a. the well-known and wide-spread power regression in the Linux 2.6.38 kernel, which has been causing many laptops to go through significantly more power than they should. This is not another workaround, but rather a behavioral change in the kernel to better decide when the PCI Express ASPM support should be toggled.
'Bout fuckin' time! Seriously, this should have been fixed way earlier. If you introduce a regression, you revert to previous version, too bad the kernel devs don't get that...
That's what they did do. They introduced a power regression to get rid of a stability regression. It was the lesser of two evils until they came up with a proper solution ie try any copy what windows does
