I just arrived at the Memorial Gardens cemetary, and have had the game freeze three times. The first couple of times through, I was looting corpses before approaching the gate for the main objective. Both times, the prompts stopped appearing when you looked at a corpse, then the loot prompt stayed on the screen and wouldn't go away. I tried pausing the game, to see if a screen change might clear things up, and that's when it froze. This happened twice. I powered the system down and restarted from the last checkpoint.
The third time, I went directly for the main objective. This time the prompts stopped at the main gate, I just continued by pressing the Use button when it was apparent I needed to interact with something. The boss battle began and the game froze when I brought up the vigor selection wheel.
I'm stopping for now, hoping someone knows a way around these glitches.
Update: Using the last strategy I mentioned, I booted up the PS3, restarted the last checkpoint and immediately ran to the main gate to see if I could somehow make it through this level. After several game freezes, I finally got to the boss fight and brute force fought my way through with the two weapons I had in stock - the Heater and a shotgun. I died a couple of times, but was able to finish without bringing up the vigor select wheel or other loot menu. I did respond to Elizabeth providing me health and salts during the battle, and fortunately that worked. I got through to an auto-save, so now I'll see if the problem was that particular map or not.
Update: Well, the last auto-save file is corrupt and hangs during load. Looks like I'm starting back at an earlier chapter.
