I've been trying to track down the exact cause and reason for these Kernel Panic / GPU restarts for a while.

MB: Gigabyte-GA-Z77X-UD5H - Video Card: Gigabyte 960GTX 2GB / Running 10.11.3 / Latest Build Of Clover as well as the nVidia Web Drivers.

Sometimes I can run the machine for a couple of hours depending on usage. Others it can be 5-10 minutes if I'm quickly switching windows/tabs or try resizing a window book.. GPU resets and I have to log back in.

I've read through a lot of posts and suggested ways to fix this issue and can't seem to nuke it for good.


Here's a couple of the errors I pulled from the log: This was right before the 10.11.3 upgrade, but the issues are still happening.

I have found several posts that mention this problem but no solutions yet.

@DJLunacy, did you ever find a solution?

What worries me is that because I'm not finding any solution anywhere that works, maybe this is a problem that can't be fixed.
