Hi, I've noticed that a great number of people have had trouble with getting
their software RAID 4/5/6 arrays to work properly with dmraid.  While
investigating this problem, I decided to recompile my kernel to see if it could
be the problem.  Lo and behold:

Now, at first, I thought it was that I tried using -O3 optimizations instead of
-O2 so I changed everything back to the way it "should" have been and ran make
clean.  Upon my next attempt, the same thing happened.  I should mention that
I'm using Ubuntu 10.10 and there are a great number of bugs they need to work
through.  But, I feel that this is more of a source code problem than an Ubuntu
problem.  Please review and let me know what you think.  Thanks!
