And if MODVERSIONS is not set?

My current theory is that setting MODVERSIONS, somehow, hides the ERROR spew.
Because that could explain your bisect. Linus' commit turns of MODVERSIONS the
hard way. And, naturally, this theory fails if your .configs never had
MODVERSIONS set in the first place.

I'm testing all this right now, but you probably command more powerful
machines and could beat me in testing this theory.

Thanks,
