pandaboard doesn't boot in LAVA with mainline kernel

Build 116 (and a few previous ones) failed to boot in LAVA:
http://validation.linaro.org/dashboard/streams/private/team/linaro/ci-linux/bundles/1974c748cb8e14f27ecaf3419bc39e31f4073a09/

Last successful boot was with build 86:
http://validation.linaro.org/dashboard/streams/private/team/linaro/ci-linux/bundles/8e0eb21f288e0a0e1c1386163b5791ec41655916/

Both hwpacks boot fine on standalone board (without master image). using the same rootfs
