ACPI share folder issue

When I specify acpi=force to boot, 9pfs mount will fail.

mount cmd:

mount -t 9p -o trans=virtio,version=9p2000.L FM /share

related dmesg:

[    0.283542] PCI: OF: of_root node is NULL, cannot create PCI host bridge node
[    3.188948] 9pnet_virtio: no channels available for device FM
