Subject: Re: [Patch V3 00/16] Enable support of IOAPIC hotplug on x86 platforms

Hi Konrad,
	We have found the root cause with your great support. If BIOS
assigns an IRQ number for a PCI device, acpi_pci_irq_enable() fails to
assign IOAPIC IRQ then due to the check:
        if (dev->irq > 0)
                return 0;
	For a quick workaround, just comment out above check. But we
need some time to figure out a clean fixup for it. We will send out new
version once it gets resolved.
	Thanks for your great help again.
Regards!
Gerry
