I don't really follow what the problem is. It might be that cgroup-v1 was not/ is not supported. We made a cut at some point. Also v4.6 is not really supported in any way https://www.kernel.org/category/releases.html I would suggest to use something more recent and try again. NVIDIA Jetson TX2 seems to be supported so a newer kernel should not be a problem. > Best, > Mohammad Sebastian
