I'm new to Ubuntu bug reporting but I think it should be better to mark this bug as a duplicate of bug #991977 that is the same bug and affect more users.
I don't understand why Christopher M. Penalver asked each user to report : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/991977/comments/26 I suppose it is to get more data to analyse the problem but it generates duplicate bugs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005160 Title: Ubuntu 12.04 hangs on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1005160/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
