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
