So, I gave Debian another chance, but it did not end well. It worked as expected for some days. Then, at a certain point, the system started becoming unreachable after a few hours (and, of course, it broke in the worst moments). I even tried to set up a cronjob for daily reboots and a watchdog, but I still had the problem.
