I saw the same thing yesterday, also when testing UCM changes :)

I was planning to bisect this myself today. But given your findings I'm not sure
if that is useful.  I would count the intermediate errors as also being bad I guess
and try to find the first bad commit and see from there.

Can you send me your git bisect log ?
