Linux kernel regression on power usage

I just installed 11.10 64bit on my Win 7 laptop but instantly i realized how hot the laptop become when i run Ubuntu. I sometimes have to boot into Windows just to cool down the laptop.

I read this was a common problem with 11.10 and that there is kernel bug( like i said i read from somewhere)

How do I solve this heating problem as clearly it has nothing to do with hardware as Windows 7 runs quite cool but 11.10 always give a massive temperature hike (not less than 55 degrees)

My Rig: HP Pavilion DV 6700 Win 7/11.10 64 bit dual boot Intel 965/ x3100 Intel Core Duo 2.0 Ghz 4gb RAM

  • No intel 965, Ubuntu has always being quiet but 11.10 is so different with this heating problem – Mysterio Oct 18 '11 at 15:34

    Same here. I just ended up using Elementary OS (based on Ubuntu 10.10). Problem occurs from Linux kernel version 2.6.37 and will eventually kill the laptop battery, or at least that's what happened to me. Could you mark this bug report as "Affecting you"? The more people are affected, the higher the bug's priority. https://bugs.launchpad.net/ubuntu/+bug/858916 – RobinJ Nov 12 '11 at 18:44
