I've just encountered this problem also. Luckily I can still SSH in to my machine and browse all my mounts. The following works for me
1. SSH in to machine 2. Kill both Plymouthd and upstart-udev-bridge 3. Alt-Ctl-Del to reboot Upon reboot you should boot up successfully however it should need to be done at every boot up. -- Not able to boot https://bugs.launchpad.net/bugs/545536 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
