Q: iMac Late 2015 5K GPU Kernel Panic during Standby

Hi,

i experience random "your computer has been restarted" messages since i upgraded to macOS Sierra.

It never happen when i work with my Mac only when it should be in Standby. Any suggestions if there

is a problem with macOS Sierra or did i get a hardware fault the same time i upgraded to Sierra?

The occurrences:

Kernel_2016-09-22-091052_wolfcastle.panic

Kernel_2016-09-26-202616_wolfcastle.panic

Kernel_2016-09-28-121200_wolfcastle.panic

Kernel_2016-10-13-120012_wolfcastle.panic

Kernel_2016-10-17-143706_wolfcastle.panic

All above kernel panics have the same "Kernel Extensions" in backtrace log which points to the GPU
