Sorry I was away for the past days.

Thanks for testing,

RBU exposes the problem, but it's still lurking even if we mask it, it's only
a matter of another interrupt being enabled and we hit that again...

Let's deal with RBU separately, I'm still not clear wether re-masking it is
the right call, now that the counter works, people may want to use that :(

I'll send a V3 shortly

Maxime
