Comment 12 for bug 908614

I encountered this issue while upgrading from 10.04 to 12.04.1 on 64-bit machine. Apparently the upgrade scripts messed up the /var/run and /run, making each symlink to the other.
lrwxrwxrwx 1 root root 4 Sep  7 13:57 /var/run -> /run
lrwxrwxrwx 1 root root 8 Sep  5 18:13 /run -> /var/run

The workaround in Comment #9 worked fine and allowed me to boot Precise. However this is a difficult to debug bug and it should likely be marked as 'High' importance.
