You don't have BB_SRCREV_POLICY set to cache anywhere do you? It
defaults to clear which is what you want...

Does "rm tmp/cache -r" 'fix' make it see new revisions? Knowing that
would at least help track down the kind of problem you're seeing.

What does the full PV look like after expansion? Does it contain an
older truncated SRCREV ?
