Hmmm...We did tons of debugging on this one and pointed it out to
IBM a while back. The ATOMIC_SYNC_FIX configuration option was the
solution to cure it. As you can tell, it tries to address the
pipeline issues surrounding the stwcx. I kind of hope it is the
problem, and a better silicon bug fix will solve it.
