the problem is since the AMD GPU doesn't official support hibernation you are pretty much the only one able to reproduce the bug. In other words I can't go to my manager to get a Cezanne system plus time to work on this. What Alex, Mario, I and all the other devs can do is to explain to you how the driver works and try to further debug what's going on here. > I'll follow up with the stack traces and additional debugging information > in the next few days.
