Hold your horses... that only talks about slowdowns, not a lockup.

Backtraces are generally not useful for diagnosing GPU lockups because they will just more or less randomly show one of the places where the drivers wait for the GPU to catch up (which never happens because it's locked up). Instead one has to focus on what triggers the lockup.
