And then I remembered I was going to mention... I spent yesterday evening trying to tempt the fail back to IVB, to no avail. So I think the underlying cause was the sporadic read returning 0 which we promptly set to rplim with the original rmw sequence. Then we falsely continued to warn during intel_sanitize_pm() due to the same sporadic read failure. So I think we have painted all the elephants here. -Chris -- Chris Wilson, Intel Open Source Technology Centre
