Right, but a kernel oops doesn't cause an array rebuild to be necessary if 
you're using a 3ware or similar RAID card. The only thing that would cause a 
rebuild would be a drive failure or a power failure (which is of course easy to 
protect against).

The software code (which I've been using for quite a while) needs to rebuild any 
time the array is not shut down cleanly, which can happen for a number of reasons.
