To be noted: I was using a balanced power state this time, not a performance power state. To be investigated.
On most cards there are only performance states. Selecting balanced also selects performance. You are probably using the same state in both cases.
This is also what it seems. However, it may be completly unrelated, but I only had hangs when using the balanced setting.
