Yeah, I checked your kernel config and it's 250Hz so I don't think that's the cause of the extra wakeups, but I'll make sure the stock kernel is also 250 tonight. I don't think it's 100, and I really hope it isn't 1000. -- Cheers, Leif -- 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
