I'm struggling to get back to a version that works on the Shark Bay / Haswell platform that I have. I did get it to work once...but have since updated the BIOS, so am not sure if that may have an effect on this test. v3.5 also gave a stack (below) - so without a working version, I cannot do the bisecting. Perhaps it is just too early in the Haswell dev cycle for me to try to get this working?
