For me it's the mtab entry for tracefs on a non-existing mount point in /var/lib/ureadahead/debugfs/tracing that is causing problems. It does affect VMware snapshots when quiescing is required too.
Since it's a different entry then in this post I opened a new bug report in #1659684 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/499773 Title: Race with ureadahead can mean that /var/lib/ureadahead/debugfs appears in /etc/mtab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/499773/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
