My log seems similar:

Already tried reinstalling the update manually and a OS-Reinstall from Boot Menu. eth0 seems dead.

pizzaboy_75, Mete0

Can you provide the complete system logs of the NAS? You may upload it to a file sharing site and then PM me the download link.

Hi,

After updating my RN214 to version 6.9.3 (readynas 6.9.2 => 6.9.3), the network interface eth0 seems to be broken, it does not pick up a link (no led) and is greyed out in the admin interface. After nas shutdown the LCD display will show do_exit+9ec. After the NAS has started, there are many cases where there is no connection to eth1 and the "NO IP ADDRESS" appears on the LCD.

I've already tried:
restart us
plug & play cable
change switch port, connect directly to PC
downgrade firmware to 6.9.2
os reinstall (boot menu)
reset to factory default
Nothing help :(

dmesg log: http://dev.a-soft.hu/dia-nas/dmesg.log.txt

Thanks for the help!

    Where do I find it? I do not know the system. Can I ask for step-by-step instructions?
