Public bug reported: I' m opening this bug as continuation of bug #760131 [https://bugs.launchpad.net/ubuntu/+source/linux/+bug/760131] (comment 188), since the power consumption in Ubuntu 11.10 is not really reduced, so the power regression in kernel 3.0.0-12 is not fixed for my hardware. Powertop shows a reduction of about 1W (from about 8W to 7W), but battery life is not really improved. Actually, battery (6 cell, Soltech PT20) life is 4h30', but it should be 6h. I'm on a Zareason Terra HD netbook [https://zareason.com/shop/Terra-HD.html], with 3G modem, 1Gb Ram, 40Gb SSD. This is a fresh installation on Oneiric (not an upgrade). I'm also adding a lshw output. Ask me for any more needed information.
