Yes, it's a known problem with rml preempt patches - DON'T USE THEM
on PPC. I sent him similar patch _two_ years ago - nothing happened.
MVL tree is IMHO better place to get preempt stuff for 2.4 - it's
actually tested and works.
Also, I wish -embedded archives were online, this problem was
discussed there around a year ago as well.
