It's easy to confirm/reject that's the "reboot" command itself:
 * Move original command to new name (e.g: /sbin/reboot.orig)
 * Put in its place (e.g: /sbin/reboot) a short script.
 * The script would simply run: "pstree -p >> /root/reboot.log"

Look at the process hierarchy in the log to find the culprit.

If this log isn't generated, that means somebody doesn't run "reboot"
but do an equivalent operation from software...
