I could be wrong about this, but I think this is the last message
printed by the Linux kernel before execution is handed off to /sbin/init
and userland.  Very very often when problems occur this is the last line
to appear.  In my experience it points to a bad /sbin/init, bad C
library in /lib, or Linux is unable to find the filesystem to run
/sbin/init.

When I built my first Busybox system I banged my head against exactly
this for several days before realizing I was using a i686 libc on a i486
and /sbin/init was not running because of it.  Thus... dead system with
"memory freed..." as the last output.  I replaced the library with an
unoptimized libc and it worked fine.

This seems like a potential FAQ... I know I see this question all time
time on this and other Linux mailing lists.
