Not that long ago (a month or so) we ran into a problem where hpacucli  
(Utility for configuring/inspecting/etc HP smartarray controllers)  
would tickle the cciss driver in such a way that it would  cause a  
kernel panic. KABLAMMO (No data loss! weeeee!).   The box had run for  
a long time without crashes, but it seems that when we added more  
disks and started the array building the new logical drive some  
magical things happened.

Bugs happen.  The [bad word] of it is catching the culprit with its  
fingers in the cookie jar.
