Actually, put it in "things that go bump in the night but need a stake driven
through them"- it looks like I booted the wrong kernel while testing, and in
fact next-20160519 *is* still broken.  However, after:

git revert -n e4f35c1339f0cfcf38d3f63dd6fea2b070399263
git revert -n 059500940defe285222d3b189b366dfe7f299cae

Things work again.
