Linux "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."

In his e-mail to the list Mr. Garrett also says that there is "zero public documentation" on this issue. I can believe that, often engineering specs are not public and must be bought from the standard body.

But I would have expected that at least one of the commercial GNU/Linux big shots, i. e. RH, Canonical, SUSE, had done so. Apparently not!

Well, sometimes you can't buy the specs because they don't exist or aren't followed by the hardware makers. And sometimes the information cannot be disclosed publicly. Put all this together and the "zero public documentation" makes perfect sense.
