I use wireless exclusively and tried the following combinations but NEVER achieved a clean shutdown.
available to all (3 users) ------------------- 1. autoconnect, connected @ shutdown available to single user --------------------- 2. autoconnect, connected @ shutdown 3. autoconnect, disconnected before shut 4. manually connected, disconnected before shut 5. networking + wireless enabled, but never connected 6. disabled networking, never connected 7. disabled wireless+networking, never connected My lsof log #1 mentions dhclient as others have. My logs #5 - 7 contain no suspect programs. But my logs #1 - 4 also implicate dnsmasq. I've included the logs from attempt #4 and 7 for what they're worth. ** Attachment added: "disconnect wireless before shutdown" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1073433/+attachment/3505332/+files/last-shutdown-lsof.4 -- 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
