Hej Angelo which release did you install? since I also would like to run my r1 and not through it away. I installed Xenial_next and it seems to run well except that after some hours the ethernet just seems to stop working its not a fixed time at least I didnt find any yet but its after 3+ hours and before that it seems to work fine ... everthing seems to work even with and sata disk in it
So i was wondering what version you run so that I might install yours and see if it hast something to do with the OS as I dont think its the power supply since I tested many and the issue is allways the same also the powerlevels in the /sys/power/axp_pmu dir look ok so this is a strange issue to me :/
would be happy for some input
