I believe it was a problem with the last two microcode releases for
Ubuntu 16.04 LTS.

That would be the 3.20191115 and 3.20191112 releases.
The 3.20190618 releases and before were ok.

Exactly which ones on 3.20191115 and 3.20191112, I don't
know without trying them, but the ones in the update stream
for Ubuntu 16.04 LTS are the ones where I had trouble.
