This didn't happen to me too much before the patch and DLC, but now it is happening very frequently. I just went home for lunch so I could eat and play some Skyrim. Had the loading screen freeze on me twice in 20 minutes.
So I'll give some basic info.
- this happens for various characters
- savefile sizes right now are 8, 7, and 6 MB
- the characters are all different styles
- PS3 Model is CECHH01
- Playing time can vary from a few minutes to a couple hours before freeze
- PS3 is at nominal operating temperature
