--- Comment #17 from Jin Yao <[email protected]> ---
Looks the IRQ value (16) is hardwired by T100 BIOS. 

Dump debug info in acpi_pci_irq_check_entry() before crash:
        0000:00:02[A] -> [16]

Dump part of ACPI DSDT table:
        Method (_PRT, 0, NotSerialized)  // _PRT: PCI Routing Table
        {
            If (PICM)
            {
                Return (AR00)
            }

            Return (PR00)
        }

        Name (AR00, Package (0x11)
        {
            Package (0x04)
            {
                0x0002FFFF, 
                Zero, 
                Zero, 
                0x10
            }, 
            ......
        }

That can explain why IRQ is used again after GPIO driver loading.
