Here are the logs from 1.13.x: https://pastebin.com/5TxUmxst
1.12.x working for comparison: https://pastebin.com/NiXnMgZ1
above has dmesg, logread, df-h
Do get this error upon first loading into a freshly flashed unit. Am flashing without preserving settings.

But error goes away upon switching pages. Also is back when flashing the working 1.12.x as well even though I am flashing without preserving settings. Does not come back on 1.12.x when I do a restore defaults.
Other issues with WD MyNet n750 and Gargoyle is that out of the 4 LEDS on the front only the Power LED is lit up. The Internet connection, Wifi and WPS LEDS are always dark.
