I have no problem with restarting or shutting down. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1002429 Title: Ubuntu 12.04 hangs on shutdown and restart To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1002429/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
