Oh - that rings a bell.
May I point you to a discussion we had earlier this year?
http://lists.infradead.org/pipermail/lede-dev/2016-May/000980.html

I had this issue on all my WRT54GLs:
trunk images stopped booting at "Starting program at 0x80001000".
However, if I compiled the images myself (with the exact same configuration
as the buildbot), the images would boot fine.
I later checked again: buildbot's images did not boot.
(It was kernel 4.1 back then, but it's the exact same behaviour as you describe
in the commit message)
Additionally builtbot's images worked out-of-the-box on an ASUS WL500gP V2.

Best regards,
