PS3 Riddle-Earth bugs/ glitches

Does anyone know a way to work around the level "Riddle Earth" I've replayed the final boss fight (because that's where it loads me) atleast 12 times because I'm determined to get past the level and whenever I finally beat the level it gets stuck in the loading screen for a good 15-20 minutes then freezes the entire console so if anyone knows a way to work past it or some how beat the level please tell.
