* Editing the system wide configuration
modprobe ltt-control
+If you want to have complete information about the kernel state (including all
+the process names), you need to load the ltt-statedump module. This is done by
+issuing the command :
+
+modprobe ltt-statedump
+
You can automate at boot time loading the ltt-control module by :
echo ltt-control >> /etc/modules
+echo ltt-statedump >> /etc/modules
