How to analyze a kernel oops on FC2

I have heard of kernel oops before but have not seen one until now. 
This is from an FC2 system.  I believe the kernel is up to date
(2.6.8-1.521 #1 Mon Aug 16 09:01:18 EDT 2004 i686 athlon i386
GNU/Linux).

System appeared to be operating normally until this occurred.  

How does one determine what caused this problem?
