Just to second this issue, the following commit is what broke this: [76acc2c1a7a9a8c2cae7e9cf8d0a8b374a48aa94] I didn't have time to delve into the whys & hows, but this commit caused the same issue on an 8572 platform. Reverting this one change allows everything (including 36-bit memory access) to work correctly, as before. -Aaron Pace
