Only a few weeks ago I started looking for the root cause of my laptop's noise and heat. I used Ubuntu Lucid 10.04 on a dual core laptop and eventually found this bug.
I tried newer kernels from https://launchpad.net/~kernel-ppa/+archive/ppa?field.series_filter=lucid Unfortunately, experience and reports (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/760131) show that 2.6.38 kernels introduce new problems. I now switched to the latest 2.6.37 from that PPA: This configuration appears to be the most silent in terms of powertop and fan noise in my experience. I'm really disappointed that the orginal issue has not yet been solved for LTS release users, more than one year after reporting. Doesn't it affect commercial clients (http://www.h-online.com/open/news/item/LVM- insurance-company-switches-10-000-systems-to- Ubuntu-10-04-LTS-1233194.html), too? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/524281 Title: Tens of wakes per second in "[kernel scheduler] Load balancing tick" on Core 2 Duo even with only 1 core enabled -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
