So in my recollection, AMCC errors often have to do with the ambient light sensor. AMCC is the Apple memory cache controller, so I'm not sure exactly how that relates to the ambient light sensor, but I have seen this referenced in more than one place.

The Ambient Light sensor is on the front facing sensor assembly, which is mounted to the display. It's not uncommon for this part to be a point of failure since its location near the edge of the display, and close to the ear speaker means it's a likely point of liquid entry and is also one that common causes restarts like this (though not necessarily with the same error).

I am going to keep doing some research, perhaps other folks have some input.
