The -19 kernel was decent; it will lock up userland whenever the machine gets too hot as above but it didn't run very hot. With a desk fan pointed at the machine I can at least get some work done.
With the latest kernel update (2.6.24-20-generic) I'm back to the issue described at the beginning, with "wakeup from idle" of about 20000 to 40000 per second. This kernel causes the machine to run at over 85 degrees when userland is completely idle, with an external fan working. As far as this overheating and freezing issue goes it is as bad as any kernel we've had so far. Possibly the worst. On the positive side, whatever changes there are between the -19 and -20 kernel must be the ones responsible for this regression, making that issue (huge number of interrupts) feasible to diagnose at least. I would really, really appreciate at least a ping on this bug comment thread to know that trying to report this is not utterly useless at least. If nobody even reads this there is no point in me trying to report it. -- Hardy kernel causes overheating https://bugs.launchpad.net/bugs/223081 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
