Bug Description
I was running an up-to-date version of Ubuntu lucid 10.04.4 LTS and used update-manager to upgrade to 12.04.1 LTS. After the upgrade was completed, a reboot of the system ended midway in a BusyBox prompt. If I type exit at that prompt the boot seems to continue as normal and the system boots to a usable (seemingly normal) desktop session. This behavior repeats on subsequent reboots. Obviously I would like to have the system boot normally and understand any underlying issue that may be causing this behavior.
For this system uname -a outputs: Linux dirac 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
If you refer to the attached version of /var/log/messages, the busybox prompt appears right after the message
Sep 15 22:42:41 dirac kernel: [ 2.696442] usb 1-3.4: new full-speed USB device number 4 using ehci_hcd
All subsequent messages occur after exiting the busybox prompt.
