Well, maybe the first thing would be to identify when or what sequence leads to
the hang. That's why I was suggesting to trace it. But if I understand you
correctly, you are saying the GPU is programmed once and then we just move from
state to another, right?
I'm not sure, but I think I've read somewhere it was possible to set a power
state manually, to force dpm to a given state in other words. Am I right?
