    Has anyone had their rMBP lock up solid, and require a hard reset? When restarting, the message below is displayed:


    This is the 2012 model with 1Gb GT650M. Looking through System Diagnostic Reports I can see a bunch of gpuRestart entries, all with the following header:

    Report Data:
                             Intel GPU Hang Summary
                                  version 1.0.0

    I can book in for a store appointment, just as soon as Yosemite is GA (Apple wont look at anything "Beta").

    Anyone else having this issue?

    Just had this happen to me as well.

    In the console I have 5 reports, 2 on the dGPU and 3 on the iGPU.

    The 2 on the dGPU report 0xd Graphics Engine Error (GR Error 5) and 0x1f Access Violation Error (MMU Error).

    The 3 on the iGPU all report the MAIN Ring, whatever that is, as the "Root Cause!"

    Don't know what any of those mean, but I have been having trouble with overheating and the laptop shutting off recently.

    Try resetting the SMC and PRAM/NVRAM. Also, run the hardware diagnostics test. There is a chance that your integrated GPU might be failing.
