Xiaomi Mi Router 3G r7519-1e83f775a3 / LuCI Master (git-18.199.46142-369553c)
i'm using a mir3g and weekly updating to the latest snapshot but from months i still having the same issue random reboots or in some cases, an amber led and what looks a freeze.
here the interesting parts i've found using /etc/syslog for logging (to avoid losing the log each reboot) when the reboots come up:
