--- Comment #13 from Rafael Antognolli <rafael.antognolli at intel.com> ---
So, trimming the MMIO reads doesn't help, I still cannot reproduce the issue.
In fact, even removing those lines that I mentioned would make it reproducible
do not really make it happen. I believe I may had a false positive, given how
hard it was to reproduce it with piglit :-/
