That's very interesting John, that could also explain why we had a system:
1) get updated
2) fail on 4.4.0-116-generic
3) work on 4.4.0-112-generic
4) install 4.13.0-36-generic and 4.13.0-37-generic
5) fail on 4.13.0-36-generic and 4.13.0-37-generic
6) get intel-microcode downgraded to 3.20180108.0+really20170707ubuntu16.04.1
7) work on 4.13.0-37-generic
