From: Thierry Reding <treding at nvidia.com> Hi, the GPU on Jetson TX2 (GP10B) does not work properly on all devices. Why exactly is not clear, but there are slight differences between the SKUs that were tested. It turns out that the biggest issue is that on some devices (e.g. the one that I have), pulsing the GPU reset twice as is done in the current code (once as part of the power-ungate
