I have similar symptoms ... running Kubuntu 11.04 64 bit on quad core. Sometimes dbus maxes out a CPU when kmail is checking for mail, but other times it doesn't seem to be associated with kmail.
Sometimes, killing the dbus process that is using 100% of CPU causes screen to blank and keyboard to be unresponsive. In those cases, I could ssh in from another box, and shut down the machine. Usually when dbus has maxed out a CPU, it is difficult to bring up a konsole terminal, and it times out instead of opening. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/680444 Title: dbus-daemon eats 100% cpu and is not responsive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/680444/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
