two and a half days of running this against both a sabre-lite and a 
wandboard quad B1 and I still have no reason to think there's any 
sort of a problem.

Up to now, my testing has been done with my own config, I'll now

I can reproduce it that way.

Suggestions on a better / easier / quicker way to reproduce it are 
welcome.
