4.15.0-45 and 4.15.0-44 do not boot. Had to fall back to 4.15.0-38

cat /proc/version_signature
Ubuntu 4.15.0-38.41-generic 4.15.18

cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"

I cannot scroll back in the hyperv console window but it seems to get to the mouse and keyboard then after some time goes to a initramfs prompt.
