Hi, I'm running the nv (instead of nvidia) driver again because of memory usage issues with xorg. In the meantime a lot changed. The bug was reported using 7.2 and I'm now using 7.3. The described freeze did not happen again. I therefore suggest marking the bug as unreproducible and close it. If I ever reach it again (and I don't think this'll be the case) I can still reopen it.
