I still to have streamline my patch consolidation process, so your getting
things like this as an artifact of that right now, sorry. That was the
correct change.

It might be the case that I need to remove some of that stuff and then
reupload the patch. I'm kind of guessing at the problem right now with
your stack dumps and it looks like the changes are causing more problems
than it is helping. Let me change that and upload something else to you
today.

Your case is particularly difficult since I don't have a machine as big as
yours that can replicate that problem and I can't do the normal kernel
stuff that I want to on it. However, I do have a good idea of what the
problem is and I'm trying to get reacquainted with the rt mutex code to
see if I can narrow it down.
