Comment (by pulkomandy):
Current status of investigations:
* hrev53759 working
* hrev53780 broken
In that range there were only two changes to the accelerant:

I see that your hardware uses "Panther Point" platform control hub. I have
adjuststed several things in the driver for "Cougar Point" which is the
previous generation. Reviewing all places where we check for INTEL_PCH_CPT
and adding INTEL_PCH_PPT where it makes sense to do the same thing is
likely to help then. I think focusing on the places in Ports.cpp for this
is a good start. So that would be lines 133, 385, 558 of the file.
