Anyone who bought Bully: Scholarship Edition may be experiencing some really big issues with massive framerate dropping, freezes, and other issues resulting in a complete system restart. This is what Rockstar told gameindustrybiz about what is going down:

We are very aware of the problems some people have been experiencing with the Xbox 360 version of Bully: Scholarship Edition and have been doing everything within our powers to resolve these issues as quickly as possible.

You have to like them nipping this problem in the bud as fast as they are. With GTAIV about a month away, the developers do not want to be dodging these questions that would certainly surmise if Bully was a complete disaster.
