Ok, so I figured it out. It's because this commit is missing in 4.9: 5e6b9a8 arm64: tegra: Add VDD_GPU regulator to Jetson TX1 > [as pointed out by Thierry on IRC, nobody has reported a bug > in the field, but using a new bootloader with a .dtb that > has the incorrect data, it will crash on boot] When I apply this patch to 4.9, the system boots successfully. The original tegra-mc page fault is also gone. So looks like it's just a matter of waiting for 4.9.1. -- Martin Michlmayr http://www.cyrius.com/
