I have 2 S3048-ON in stack, and after 1 year without reboot, we turn off and turn on the switches, and one switch dont back more. On startup switch show errors and reboot again and again...

I try to uninstall ONIE and install again, but I cant install because receive errors about cannot read /dev/i2c-2, unable to found serial number  and not found base mac address

Ideas about this problem?

errors on boot:
