Starting with this patch, my Lenovo Thinkpad X121e netbook (it's without
any mute LEDs, BTW, there is only a power LED) considers the power
button as hard reset. I have to exclude my machine from that ACPI fixup
(this is on top of current Linus master):

Is that the way to address it? Then I can send a proper patch. Any hints
regarding the "why" will be incorporated into its description.

Thanks,

It seems more like a firmware issue, in the acpi code, the "SSMS" is for
mute led, and the "MMTS" is for micmute led, I don't know why your
machine can pass "SSMS" or "MMTS" scanning even without mute LEDs.

Is there anything I can debug or any information I can collect from my
box to examine this?

What is the linux distribution on your machine? And use showkey to catch

I'm running OpenSUSE 13.1. The reported keycode of the power button is 116.

It seems the keycode is correct, it is power keycode rather the mute
keycode.

Could you please do some debug, let us find which line of code is the
root cause for this problem. for example:

after running the line, the problem shows up:

1. if (ACPI_SUCCESS(acpi_get_devices("LEN0068", acpi_check_cb,
&found, NULL)) && found) // in the sound/pci/hda/thinkpad_helper.c,
is_thinkpad()

2. return ACPI_SUCCESS(acpi_get_devices("IBM0068", acpi_check_cb,
&found, NULL)) && found; // same as above

3. if (led_set_func(TPACPI_LED_MUTE, false) >= 0) { //in the
sound/pci/hda/thinkpad_helper.c, hda_fixup_thinkpad_acpi()

4. if (led_set_func(TPACPI_LED_MICMUTE, false) >= 0) { // same as above

This evaluates to true

If we change the code like below, does the power button can work well?

in the thinkpad_helper.c, hda_fixup_thinkpad_acpi()


if (led_set_func(TPACPI_LED_MUTE, false) >= 0) {
/*
old_vmaster_hook = spec->vmaster_mute.hook;
spec->vmaster_mute.hook = update_tpacpi_mute_led;
removefunc = false;
*/
}
if (led_set_func(TPACPI_LED_MICMUTE, false) >= 0) {
/*
if (spec->num_adc_nids > 1)
codec_dbg(codec,
"Skipping micmute LED control due to several ADCs");
else {
spec->cap_sync_hook = update_tpacpi_micmute_led;
removefunc = false;
}
*/
}


If power button can work well, please uncomment one section of the code
to find which section code introduce this problem.

Hui.

Disabling only this block resolves the issue.

So Below two lines make the power button change to the reset button.

drivers/platform/x86/thinkpad_acpi.c mute_led_on_off():

acpi_get_handle(hkey_handle, "SSMS", &temp);
acpi_evalf(hkey_handle, &output, "SSMS", "dd", 1);


@alexhung,
Do you have any idea why this can affect the power button behavior?

I think we all lost track of this issue, but it unfortunately still
exists in the latest kernel, requiring custom builds here. How can we
proceed?
