Hi Lv, The Asus X550ZE laptop does not trigger EC events, resulting in non-working Fn keys and inability to detect lid close events. From /sys/firmware/acpi/interrupts/ I observe that GPE 0x15 is continuously increasing, but no _Qxx methods are invoked. Any idea what to try? The original bug report is at https://bugzilla.kernel.org/show_bug.cgi?id=115021 More debug dumps can be found in https://lekensteyn.nl/files/Asus-X550ZE/ Reproduced with various kernel versions including 4.6.3, 4.7 and v4.8-rc2-348-g6040e57. -- Kind regards, Peter Wu https://lekensteyn.nl -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
