hello,
my orangepi3 after the updates of firmware of these days seems to loose eth0, at reboot take eth0 and eth0:avahi with class 169 ip.
i made backups (i use a sd to restore the mmc mouting hd and then copy the gzip image) so i have not problems to restore but, i suspect, the previus version is working but the new one not.
sorry for my worst english...
ab
