I see many platforms succeed in lab-khilman, but fails in your farm as
well :(

For example:
http://storage.kernelci.org/next/next-20150119/arm-imx_v6_v7_defconfig/lab-khilman/boot-imx6q-wandboard.txt
has the same errors, but marked success.
http://storage.kernelci.org/next/next-20150119/arm-imx_v6_v7_defconfig/lab-tbaker/boot-imx6q-wandboard.txt
is marked fail.

I suppose this is much worse than the "pass" status indicates.
