My latest report on this saga including summary of past repairs:
Repair 1: 2014 - took machine to store, for 1 week they had it running but could not reproduce issue.
- took back home
Repair 2: - took machine to store, they replaced video cards, and other components. After they had the machine for 5 weeks I cried so hard they gave me a new machine.
2015 - Machine crashes every 2 days or so:
DumpGPURestart[3623]: Saved gpuRestart report for kernel to /Library/Logs/DiagnosticReports/Kernel_2016-12-09-130919_mammoth.gpuRestart
- - I mostly ignore the problem while my ulcer grows in size.
2016:
- Repair #3 - Take machine to store, GeniusBar diagnostics finds no trouble (no surprise there) they refuse to take the machine in, instead have me take it home so that I can capture data for engineering.
- Repair #4 - Engineering sees the logs and deems one card as faulty. Apple replaced both D300 cards for the D700 model.
