I agree completely. I mentioned this because of
dmsg_ovmf.log: ACPI: PCI Interrupt Link [LNKA] (IRQs 5 10 11) *0, disabled.
dmsg_ovmf.log: ACPI: PCI Interrupt Link [LNKB] (IRQs 5 10 11) *0, disabled.
dmsg_ovmf.log: ACPI: PCI Interrupt Link [LNKC] (IRQs 5 10 11) *0, disabled.
dmsg_ovmf.log: ACPI: PCI Interrupt Link [LNKD] (IRQs 5 10 11) *0, disabled.
dmsg_ovmf.log: ACPI: PCI Interrupt Link [LNKE] (IRQs 5 10 11) *0, disabled.
dmsg_ovmf.log: ACPI: PCI Interrupt Link [LNKF] (IRQs 5 10 11) *0, disabled.
dmsg_ovmf.log: ACPI: PCI Interrupt Link [LNKG] (IRQs 5 10 11) *0, disabled.
dmsg_ovmf.log: ACPI: PCI Interrupt Link [LNKH] (IRQs 5 10 11) *0, disabled.
