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? -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
