> What's wrong with /tmp now?! That's a very good question. But it has nothing to do with upstart; for some reason, /proc/mounts on your system reports a tmpfs mounted at "/tmp/auto6FJPRq (deleted)", which it can't unmount, and as a result /tmp can also not be unmounted cleanly. What's unusual is that something on your system was able to delete the mount point of an active mount. This shouldn't happen at all. So you may be looking at a kernel bug, or a bug in sysvinit-utils (which handles the unmounting at shutdown). If you can reproduce this issue, please file a new bug report against the sysvinit-utils package with details. It is certainly unrelated to the common issue being described here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1073433 Title: Ext4 corruption associated with shutdown of Ubuntu 12.10 To manage notifications about this bug go to: https://bugs.launchpad.net/upstart/+bug/1073433/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
