In addition a workaround is to disable kernel options for virtio for a custom kernel config:
# VirtIO support
# device virtio # VirtIO core
# device virtio_blk # VirtIO disk driver
# device virtio_pci # VirtIO transport over PCI bus
Attached is a dmesg for the booting configuration with acpi and virtio disabled.
