Hello all,

A while back i have created a ticket
(https://dev.openwrt.org/ticket/17609) detailing kernel 3.14.x failure
to boot on ar71xx (wndr3700v4 router) platform. Today i have
successfully used serial console attached to the router and got a boot
log which shows a wrong checksum of kernel image when trying to attach
it from UBI to MTD, please see output below ... i hope this helps in
identifying and narrows the issue for a possible fix.

Cheers!
-paul
