Two of the kernel hangs, note one is an OOPS, while the other is not, I was able to shut down the machine normally after the first OOPS as the kernel was still responsive to power button events.
When running OpenGL applications with PRIME, the screen freezes and a kernel OOPS is generated. This seems to happen either when the application starts, or the window of the application is re-drawn (moving workspaces, minimizing/maximizing) Crashes seem to be inconsistent as sometimes the kernel just freezes and no OOPS is generated.
Archlinux with kernel 3.19.1-1
Below is an attached kernel log with _TWO_ separate kernel hang, both caused by running an OpenGL application with PRIME.
Please attach your full dmesg from boot, xorg log, and lspci -nn output.

Another crash, this time with running 4.0.0 kernel, which also gave me a trace.

Same crash, this time with 3.19.2-1 kernel. Notice the mention of i915
I just downgraded, PRIME worked flawlessly up until 3.19, I was able to test up until 3.17.6-1 since the next one after that was the latest kernel in the [testing] repo aka 3.19.2-1

Can you narrow it down further, ideally bisect?

I guess I could try, but not in the near future as I lack free time. Will report back once done or when any progress is made.
