Normally, this should be very easy for you: any non-zero number of
failures indicates a regression.

However, we've recently added a few more board farms to kernel CI which
have boards that work with newer kernels, but not older/stable kernels.

We need to blacklist these new boards from stable testing until they are
known to work, so they don't show up as false positives.

Sorry for the noise.  Until we sort out the blacklisting, I'll try to
follow-up on these with an interpretation of the restuls.
