so apparently no failures before d942e43b58 and no passes after b172e38.

so there are two failures with that one revision, panda18 and beaglexm03
neither of which have a pass afterwards.

This data suggests that it's not failing boards, unless they are
sometimes ok, sometimes not.

It suggests that there may be a non-deterministic failure caused by the
kernel.

Cross-referencing the set of patches

  in d942e43 but not in 9c1f859 in linus

with those

  in bdb4245 but not in dfa690c in arm-soc/for-next

may give some clues.

Thanks,

James
