I am using FC5 update kernel.  So you could be right.  I hav enot been able to 
catch any syslog info on the issue, so hardware is very difficult to 
troubleshoot.  I have moved the raid around ( different bus etc.. ) changed 
the power supply but would like to get more info somehow.  I can crash the 
system by moving a mass stream of data off/on the server, so load or FS 
reading/writing etc.. 
Ideas on how to proceed with more hardware troubleshooting?
Have you found XFS more performant thatn ext3?
