Shutting down and "restarting because of a problem" during sleep
Lately my 305 GHz Quad-Core i7/16GB RAM/NVIDIA GeForce GTX 780M iMac has been regularly shutting down on its own during sleep. By the time I wake it, it's restarted on it's own with the problem report up. Any suggestions out there? Here's the report I'm receiving regularly:
panic(cpu 2 caller 0xffffff80032a1c6c): Sleep transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.iokit.IOGraphicsFamily. Thread 0xd17cf.
Failure code:: 0x00000002 00000014
The rest of the report is below:
