2013 MacPro - GPU hang failure to restart GPU
I purchased a 2013 MacPro and I was having frequent GPU Hangs. The symptom is the screen would be frozen but I could login from remote via ssh (not screen sharing) and see the system.log was spewing about not being able to restart GPU, and that the GPU had hung.
I went back and forth with applecare over it and after some failed debugging attempts including re-installing I returned the mac pro and they sent me a new one.
The original macpro would crash every day or so. I've had the new one a few weeks and it just crashed today with the same message for the first time.
I never really got to the bottom of which it was happening with AppleCare. Has anyone ever seen this be a software problem? I am using the DualLink DVI adapter which is not what I would call a quality product, but I'm not sure I see how it could be causing this.
I'm going to call AppleCare again about it but I wanted to see if anyone else had faced similar issue. I haven't seen much about it with searches.
Here is snippit from log.
