So.... it turns out I'm as affective at off-by-one errors in git
bisect as I am in coding... :/

It turns out the commit with the issue was:

commit 1628082c6b882d064bd5d77e5847c42b44b59fde (HEAD, refs/bisect/bad)
Author: jdolecek <>
Date:   Mon Oct 22 21:04:53 2018 +0000

    enable MSI support where available
