kernel panic:attempt to kill the idle task!

[Robin Gerard <robin.jag@free.fr>]

 Hello,
 since a while my hard disk works without any task be 
 launched and afterward my computer crashes with the  
 message that I put in attached document.
 When I reboot, fsck check and repairs the file system
 and finally all seem correct.
 How can I know if this problem result from my 
 computer or other causes, and how can remediate this problem.
 TIA
