Very strange. Is this from the yocto master branch ?

validate branches will always dump out an error message if it finds
a mismatch in the SRCREV and branch(s).

I've seen this myself in the past. It triggers when the kernel tree that
is being used is for some reason missing the branches in question and
the default bitbake behaviour that if any command returns non zero, the
entire function fails.

I have two commits that attempt to detect this, and do a proper warning,
I just haven't sent them out yet due to travel.

That being said. If you go into your src tree. Do you see the meta and
board branch ? Are they local branches ? Is your SRC_URI pointing at a
bare clone, and not a non-bare one ?
