I have found that this bug is related to X: without that there is no problem!
I have accidentally deleted the nvidia kernel module, thus my laptop booted into text mode. Then I run the powertop dump and the [kernel scheduler] Load balancing tick is down to 1,6 from 64,2 with X with the same official Ubuntu 10.10 2.6.35-22 kernel! Logs attached, hope this finally helps to fix it! Should you need more testing contact me. I think that the importance of the bug should be high, since it makes a vast difference in the battery runtime for all laptop users! ** Attachment added: "powertop-dump-5min-noX-2.6.35-22-generic.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/524281/+attachment/1722655/+files/powertop-dump-5min-noX-2.6.35-22-generic.txt -- Tens of wakes per second in "[kernel scheduler] Load balancing tick" on Core 2 Duo even with only 1 core enabled https://bugs.launchpad.net/bugs/524281 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
