Which devices do this? The ability for a device to raise an ACPI GPE and trigger a wakeup does not imply that there's runtime handling for that device's GPE in the system's ACPI tables. The default GPE handling code I posted for Intel helps here, but there's ample opportunity for us to find machines which have system wakeup support but no runtime wakeup support. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
