Colin, that was an interesting read on bug 177895. I think that in those comments there are two separate issues: 1. People complaining about "<kernel IPI> : Rescheduling interrupts" 2. Some people noticing the larger interrupt count caused by the issue on this bug report (possibly yenta_socket).
Anyway, I've got the three logs to attach here. I made sure that when I was capturing the logs that powertop had seen the system go into "crazy" mode with 10-20k interrupts/sec. I can't see *anything* unusual in the logs :( It's looking very much like a kernel bug *somewhere*, particularly since reloading yenta_socket will fix it, albeit temporarily. Cheers. ** Attachment added: "irq_delta.log" http://launchpadlibrarian.net/13327731/irq_delta.log -- Powertop reports huge number of wakeups and drains battery https://bugs.launchpad.net/bugs/145377 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
