Big fix is the duct-tape for ring init on g4x platforms, we seem to have found the magic again to make those machines as happy as before (not perfect though unfortunately, but that was never the case).

I unfortunately don't agree with the last part; there are older kernels (such as 3.7) where I have never ever seen this ring initialization failure, despite it being excercised very heavily (hundreds of suspend/resume cycles on the machine I am debugging this problem on).

As I said in the bugzilla already, the affected machine will be physically present in my bag at the Kernel Summit, in case it helps you guys from Intel to debug it.
