The CPU will automatically throttle when a certain temperature is
reached. This may be the cause of the lockups.

Have you tried ondemand mode? It ramps up the speed faster than
conservative mode and drops equally fast if there is not much to do. I
have it enabled everywhere and didn't notice any problems.
