Are these (other than noapic) workarounds really enable APIC controller? With acpi=noirq only PIC and MSI entries present in /proc/interrupts. So I assume acpi=off does the same. While noapic obviously disables APIC but works fine for me. Looks like ivrs_ioapic... enables APIC, but in my case system is very slow and even not always boots. Is disabled APIC have significant drawbacks (while most of devices placed on MSI-routed PCI lanes)?
