Yung found that some platforms use the pciehp driver instead of acpiphp one. And I tried to find what's the difference. The answer is the platform using pciehp uses irq 41, the PME pciehp, and the one using acpiphp uses irq 9, the acpi default irq. So, what reason make the difference? The platform uses acpi irq #9 as shared irq because of irq's scarcity.
