I have identified the bad commit: plex linux-git # git bisect good 84245af7297ced9e8fe837dc0fc4782438771bd2 is the first bad commit commit 84245af7297ced9e8fe837dc0fc4782438771bd2 Author: Jiang Liu <jia...@li...> Date: Tue Jun 10 14:14:47 2014 +0800 x86, irq, ACPI: Change __acpi_register_gsi to return IRQ number instead of GSI Currently __acpi_register_gsi is defined to return GSI number and may be set to acpi_register_gsi_pic(), acpi_register_gsi_ioapic(), acpi_register_gsi_xen_hvm() and acpi_register_gsi_xen(). Among which, acpi_register_gsi_ioapic() returns GSI number, but acpi_register_gsi_xen_hvm() and acpi_register_gsi_xen() actually returns IRQ number instead of GSI. And for acpi_register_gsi_pic(), GSI number equals to IRQ number. So change acpi_register_gsi_ioapic() to return IRQ number, it also simplifies the code.
