Hi Marc

Maybe take a look at your memory barriers. Most accesses using the
_relaxed() version, i.e, no barrier. And then there are specific
barriers when needed. One could be missing.

As a quick test, drop the _relaxed. Force a barrier with each
access. If that works, it is a clear indication you have a barrier
problem.
