Kernel trouble

[mandar satam]

Hi ,
 
 
   I have a wierd problem.I am trying to make  changes to freebsd 5.2 scheduler to make it a user based fair share scheduler as a part of my project.I have created a data structure similar to runq datastructure.My problem is that when I compile my changes into the kernel, the kernel reboots again and again and gives me a fatal trap error befroe rebooting each time.
 
    Could someone explain why this happens?Thanks & Regards, 
Mandar Satam
