System boots to busybox after 10.04 -> 12.04.1 upgrade
Status in “update-manager” package in Ubuntu:
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
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.
