I'm not now convinced the kernel isn't spamming us. Can you do the following:
1) sudo stop upstart-udev-bridge 2) Plonk the attached bug-850935.conf into /etc/init/. 3) Reboot with the battery attached. bug-850935.conf will create a file /tmp/bug-850935.log with 1 line for every "power_supply-device-added" event emitted, but will stop logging if it sees >10 such events. If that file contains >1 entry, the bug is with udev or the kernel. There is a secondary bug which is triggering the dbus assert failure, but I'm not clear yet if its in Upstart/nih or in dbus itself. ** Attachment added: "upstart job config file to log power_supply-device-added events." https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/850935/+attachment/2412359/+files/bug-850935.conf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/850935 Title: upstart-udev-bridge at 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/850935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
