Thanks!

That's okay.  I don't think you should bother.

I am satisfied, because now it's clear (1) the problem was in the
kernel, (2) the problem is actually fixed (not just a change in what
the remote repos were serving, for example), and (3) there was at least
one kernel change meant to address similar problems.  It would be
lovely to confirm on some other machine that reverting that patch
introduces the errors, but even that does not seem necessary to me.

Thanks for tracking this down.

Pleased,
