Comment 6 for bug 1266494

The failure is due to wrong bootargs being passed by LAVA while booting the kernel:
console=tty0 console=ttySAC2,115200n8 drm_kms_helper.edid_firmware=edid-1920x1080.fw root=UUID=cba9023b-4606-4489-9e22-d5caa4cb6414 rootwait ro mac=02:74:0c:d6:16:33

The actual bootargs should be:
console=tty0 console=ttySAC2,115200n8 androidboot.hardware=exynos5250-arndale rootwait ro rootdelay=3 init=/init androidboot.console=ttySAC2 fbdev=/dev/graphics/fb2 console=ttySAC2 root=/dev/mmcblk1p2 mac=02:74:ac:95:16:33

Someone from the LAVA team should address this issue.
