FS#1686 - Mir3g random reboot/freeze

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:

I also regularly observe reboots with my Xiaomi Mi 3G unit. Haven't found any correlation between reboots, they are quite random. The only clue - reboots frequency depends on a number of connected clients.

Build info:
