<pre>So far it's looking good with csb_force_mmio returning true and traces off. I
did try another run without that hack and it had the system hang on the first
run.
But so far after adding the return true; there, it's been stable for 7-8 runs.
I'll leave it running the whole day just to be sure.</pre>
