Bug Description

To reproduce:

 * start a bionic VM in azure:
az vm create --name bionic --resource-group test-bionic --image "Canonical:UbuntuServer:18_04-lts-gen2:latest" --size Standard_M416s_v2 --admin-username ubuntu --ssh-key-value SSH_KEY_PATH

 * "downgrade" the kernel to 4.15 and delete the 5.4 kernel

 * reboot (the machine should fail to boot)

The serial console logs can be found on the azure portal (boot diagnostic needs to be enabled for the VM first).
