issues with nMP

[teagls]

Hey all,

I've been having issues with my nMP the past few weeks and it seems to be getting progressively worse. The most serious issue is a complete system lock that requires a hard reboot.

I dug a bit into the logs after such an event and noticed a lot of entries like this. It appears the OS tries to reboot the GPU multiple times but is never successful. I fear this is a hardware issue and the GPU is failing. Does anyone have any experience as to what this could be?

It could also be a driver issue but I wouldn't spend a bunch of time trying to figure it out. Just print the logs and go to the Apple store (this assumes it's under warranty)
