Hi, all I tried to set the register to trigger a SCI. But the system crashed with output: [ACPI]Error (evgpe-0711): No hander or method for GPE [2],disabling ...... Did I set wrong register? The system's ioports map is different from ACPI register map defined in Intel ICH8 manual. My kernel version is 2.6.18. Any suggestion will be appreciated.
