Is there a specific scenario that causes the kernel to oops if an MD device is 
made of DM devices? EVMS has been using this kind of configuration for a 
couple years, and we've never noticed a problem with it. Also, syrius 
mentioned on IRC that this problem only started occurring with -ac10, and 
that -ac8 worked fine. I'm checking out the diffs between those two versions 
to see what else might have changed.
