    What are your system specifics and how are you determing draw?

    Wow, all you people are retarded, this was an intel issue and the reason that they disabled that by default is because it was still buggy. Blaming linus for something that was clearly a smart decision by the Intel DRM devs. They chose stability over power consumption, its as easy as that. Its the same thing with the ASPM power regression by defaulting to it being enabled they had issues arise so they had to fix the issues. Yes it sucks for those who didn't have those stability issues with it enabled but at least it has a better chance of it working for those who did.

    Also I know for a fact that Michael has said he doesn't report bugs of bisect things because it would take time from writing articles and gathering the data within them. He rarely digs deeper into the issues by doing things like bisecting or finding an linking to relevant upstream bugs, in fact he rarely even links to where to find more info, though once in a while he'll include a link to the relevant ML. The articles only "links" are just links to his older articles, which is fine, but he spams them so much without linking offsite or to sources it seems he is just trying to get more page views and thus more ad revenue rather than trying to actually inform the reader better.

    I can see Linus releasing RCs leading up to 3.1 and saying: "oh nothing interesting in this release...and other bullcrap" instead of doing something about the regressions that would benefit regular users.

I got a new netmook that came with Windows 7 and the reason im sticking with the os is battery life. I get a hole extra hour. At this rate I'll have a better power consumption under Haiku Os.

    Yeah. Sitting at a terminal with most hardware not having drivers would make for a pretty efficient system j/k

    IBM, Google, RedHat? Where are you?
    Why would they care about laptops? IBM only sells servers, Google only uses servers or mobile phones (platforms where this power regression doesn't come into play) and Red Hat mainly focuses on servers. I think the big question is where Ubuntu is, they should be the ones that has most customers targeted by this issue right now.

    No matter how you look at it power consumption under linux seems to be getting pretty ignored. A second class citizen.

    So since this regresions have been discovered no developer noticed them even if they have been higly present in the media.
    I would love to solve the bugs myself but I'm an arhitect I have no idea about brograming. This is a problem too comon present in the linux world. Noone cares about users that are jsut users we aren't programers. And these bugs usually afect us the most.

    Yes, but if you would read the whole discussion (and the article) you could see that the regression related to a small commit disabling the power-saving feature off the "Sandy Bridge"-graphics. And this step was made to get rid of some nasty bugs and system hangs.

    As Michael stated himself, only his system with the "Sandy Bridge"-CPU has a higher power consumption. The older Core i7-system with a Nvidia graphics card has the same power consumption as Linux 3.0.
