But according to the irq router in pci conf, 
the ehci and audio share to use irq 20.
sata0 and ohci use irq 23
sata1 use irq 22, (MAC1 share it but kernel will use MSI)
sata2 use irq 21, (MAC0 share it but kernel will use MSI)

the ACPI report wrong GSI for them?

Can you disable the acpi and check the interrupt and lspci?
