I also see a lot of "[Reschduling Interrupts] <kernel IPI>" in powertop. Yesterday I was using Karmic and, when idle, powertop would show as few as 25 interrupts per second in total.
After upgrading to Lucid, I get between 150 and 500 int. per second from "[Reschduling Interrupts] <kernel IPI>" alone. Load balancing tick interrupts have gone up as well. My laptop CPUs are 6-7 ÂșC hotter than under Karmic, and the fans are almost always on. Lucid has disappointed me so much only with this bug that I'm considering downgrading. -- multi core laptop system overheating, powertop showing a lot [Rescheduling interrupts] <kernel IPI> https://bugs.launchpad.net/bugs/552020 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
