The underlying problem is that, at system shutdown time, dhclient isn't given the opportunity to gracefully exit, closing any files it has open. This causes /etc/init.d/umountroot to fail. When umountroot fails, the filesystem must be recovered.
There is, to the best of my knowledge, nothing particularly unusual with the various installs of 12.04 that I've been testing, and the problem is evident with all of them. One difference might be that I have the splash screen turned off in grub and so can see the messages. Maybe that explains why you're not seeing them. At some point, possibly in oneiric, changes were made which put the dhclient pid in /var/run/sendsigs.omit.d/ and I believe that's the basis of the problem. And it IS a problem - the root filesystem should not need recovery on every reboot. The "orphaned inodes" messages are just icing on the cake. Do "sudo apt-get install --reinstall libc6" then reboot, and run "dmesg | grep EXT" and you should see the messages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/963106 Title: NetworkManager causes orphaned inodes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/963106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
