That would make sense if you have an R420 GPU, this is a known erratum
of that core. Stefano has an RV350 though, which isn't affected by this.

Unfortunately there's a virtually unlimited number of problems that can
cause GPU lockups, and people tend to focus too much on the symptoms
(which tend to be similar) rather than the causes / triggers.
