Test result is unavailable since build 486 on Samsung Origen ubuntu image.

Looks like origen images no longer have a valid device tree:

build 482 is using 3.6 kernel, while 486 is using 3.7:
linux-image-3.6.0-1-linaro-lt-origen_3.6.0-1.1~ci+121020091538_armhf.deb
linux-image-3.7.0-1-linaro-lt-origen_3.7.0-1.1~ci+121119220221_armhf.deb

the device tree is only available in 3.6 package.

fix commited, debs are building in kernel ppa
