    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

    Other regressions

    [quote]
    That's one regression now addressed, with only several more power management issues left in the kernel...

    Did you find those other regressions with git-bisect?

    Finally.

    Actually I was planning to e-mail LKML with my solution to the problem, a white-list of ASPM supported devices on computers with a proper BIOS, which could be collected through Phoronix Test Suite.

    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.
