Good to hear that Intel is working on this; thanks for the update. I would like to point out, however, that this power problem has two separate symptoms that add up to give the huge power loss. The first is disabling rc6 (on Sandy Bridge) in kernels 3.x. The second has to do with "sparse irq" in the 3.x kernels causing excessive processor wakeups (also on Sandy Bridge), as documented in this related/duplicate bug's description: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/834037
Should I file a new, separate bug report for the sparse irq problem? I thought the two problems might be related, but maybe not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/818830 Title: [Sandy Bridge] serious power regression from kernel 3.0.0-6 to 3.0.0-7 (rc6 disabled) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/818830/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
