I'm getting this same issue in my strip mine in a specific spot. FPS drops to 0. log says "[08:41:56] [Client thread/INFO]: Warning: Clientside chunk ticking took 1839 ms" repeatedly, like in the bug description. After exiting the map and reentering, the problem doesn't start back for a few seconds (giving you time to escape to a safe distance). However, if you reenter the area, the problem starts back. My mine is at y8, but going to the same coordinates at y62 does not cause the problem.
I've noticed this in other places since updating to 1.7, but this is the only spot I've been able to reproduce reliably. This is on a server.
