There are various posts on the official UT3 forums saying that one of the user created mods 'Cooked' by Epic games is crashing PS3's.
People are pointing towards the 'Mutator' mod that was released.
As this is a user mod it is unclear who will look into this problem as if Epic look into the problems they will simply be a free testing arm for PS3 user mods and this task will become impossible once they release their utility for pc users to cook mods themselves.
