I also observe regular hangs when I try to shutdown the system (12.04). I have normally mounted several cifs-shares.
I generated a kernel core dump when the computer seemed to hang during shutdown. Among a few remaining userspace processes where S31umountnfs and umount. Looking at umountnfs.sh revealed, that it does not just unmount nfs shares, but all kind of network shares (like cifs, coda, etc). I suppose the problem is that the interface connected to the share is already down when the script is run, which then leads to blocking shutdown. As a try to work around this problem, I set "Available to all users" in network manager for the connection in question. On a quick test, this seems to work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/859075 Title: Oneiric does not shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/upstart/+bug/859075/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
