<pre>SandyBridge and IvyBridge are really two different beasts when it comes to the
GPU. There are a lot of similarities, but the silicon is more than just an
evolution of the SandyBridge design. Just to put things in perspective.
So that IVB is stable unlike SNB, doesn't rule out any part of the stack.
Hopefully we can find a way to prevent the lockup, and to find a way to reset
the GPU after the hang, and fix the hangs in the first place!</pre>
