Thanks for posting this, I am glad to know that this is a common problem. i was starting to worry i needed to get my PS3 serviced. I downloaded this from plus and i am still having this issue.
Hopefully, more people will post this problem. Is not the controller, neither the game data or save data. I uninstalled the game and erase the game and save data and it still happening. And the lock or freeze is different. Is the one that you press the power button to stand by or turn off and it stays on with green light blinkin like twice a second and nothing happens and I need to unplugged the ps3. HATE unpluging the PS3 while on!!!! Please Sony, take care of it cause if my ps3 gets damaged because of this you wont give me a Free PS3!
I'm really kinda surprised this hasn't been patched. I mean, it seems like a pretty major bug, plus it is getting a lot of attention now that it is part of PS+.
