Hello!

With new 3.19-rc1 kernel every time when I open LID on my laptop, kernel prints these error lines to dmesg:

With older kernel (3.13) I do not see these errors, so it is regression. Can you look at it? If it is needed, I can provide other logs, ACPI/DSTD dumps, etc.

Pali,
Do you known how to run git bisect as this is probably the best way to continue. Otherwise, I can teach you how it's not hard if your willing to learn :). Cheers Nick

I know how to use git... first I wanted to report errors because maybe it could be known problem or somebody else can come with quick patch even without bisetcing (like for other problems which I reported).

Anyway those acpi devices which are mentioned in log do not exist in 3.13 kernel (I do not see them in /sys/devices)

Any idea why 3.19 kernel create new acpi devices which 3.13 kernel did not?

Pali,
This was probably to either add better power management or enable some new features related to acpi. Can you send me the files they created in kernel 3.19 r1 as I can probably trace it back to the bad commit. Regards Nick

All of the above mean that power transitions were not carried out for some devices, because they were in unexpected power states to start with.

They are devices on the Intel LPSS as far as I can say (CCing Mika and Andy).

With older kernel (3.13) I do not see these errors, so it is regression.

It only is a regression if it leads to functional problems. Do you see any?

Quoted 2 lines

Ca=n you look at it? If it is needed, I can provide other logs, ACPI/DSTD dump= s, etc.

It looks like 3.13 didn't try to use some devices that are now used in 3.19-rc1 and something doesn't work entirely as expected.

Hello!
With new 3.19-rc1 kernel every time when I open LID on my laptop, kernel pr=
ints these error lines to dmesg:
Does your syste suspend when the lid is closed and resume when it is open?

No, I disabled all autosuspend and autohibernate settings. When I close LID system is running.

In reply to nick

Hello,

in attachment is output of ls -l /sys/bus/acpi/devices from both 3.13 and 3.19 kernels.

Anyway Gabriele Mazzotta wrote me that new acpi devices could be created after commit faae404ebdc6bba (ACPICA: Add "Windows 2013" string to _OSI support).

Maybe this another output could help you:

$ cat /sys/bus/acpi/devices/INT33C5\:00/status
0
$ cat /sys/bus/acpi/devices/INT33C5\:00/power_state
(unknown)

Device INT33C5 is in that dmesg log:
acpi INT33C5:00: Cannot transition to non-D0 state from D3

And status 0 in sysnode could indicate that acpi device is not present right?

Pali,
This was probably to either add better power management or enable some new features related to acpi. Can you send me the files they created in kernel 3.19 r1 as I can probably trace it back to the bad commit. Regards Nick

I know how to use git... first I wanted to report errors because maybe it could be known problem or somebody else can come with quick patch even without bisetcing (like for other problems which I reported).
Anyway those acpi devices which are mentioned in log do not exist in 3.13 kernel (I do not see them in /sys/devices)
Any idea why 3.19 kernel create new acpi devices which 3.13 kernel did not?

Pali,
This seems to be a likely culprit. Would you mind building a kernel before that commit was merged in order to test if it works.
Regards Nick

Hello,
in attachment is output of ls -l /sys/bus/acpi/devices from both 3.13 and 3.19 kernels.
Anyway Gabriele Mazzotta wrote me that new acpi devices could be created after commit faae404ebdc6bba (ACPICA: Add "Windows 2013" string to _OSI support).
Maybe this another output could help you:
$ cat /sys/bus/acpi/devices/INT33C5\:00/status

Device INT33C5 is in that dmesg log:

And status 0 in sysnode could indicate that acpi device is not present right?

Pali,
This was probably to either add better power management or enable some new features related to acpi. Can you send me the files they created in kernel 3.19 r1 as I can probably trace it back to the bad commit. Regards Nick

I know how to use git... first I wanted to report errors because maybe it could be known problem or somebody else can come with quick patch even without bisetcing (like for other problems which I reported).
Anyway those acpi devices which are mentioned in log do not exist in 3.13 kernel (I do not see them in /sys/devices)
Any idea why 3.19 kernel create new acpi devices which 3.13 kernel did not?

With older kernel (3.13) I do not see these errors, so it is regression. Can you look at it? If it is needed, I can provide other logs, ACPI/DSTD dumps, etc.

Device INT33C5 is in that dmesg log:
acpi INT33C5:00: Cannot transition to non-D0 state from D3

The appended patch should make these messages go away, please test.

And status 0 in sysnode could indicate that acpi device is not present right?

That's correct.

 	int result;
 
 	result = acpi_bus_get_device(handle, &device);
-	return result ? false : device->flags.power_manageable;
+	return result ? false : acpi_device_power_manageable(device);

This might read better as:

	if (acpi_bus_get_device(handle, &device))
		return false;

	return acpi_device_power_manageable(device);

Hello,
in attachment is output of ls -l /sys/bus/acpi/devices from both 3.13 and 3.19 kernels.
Anyway Gabriele Mazzotta wrote me that new acpi devices could be created after commit faae404ebdc6bba (ACPICA: Add "Windows 2013" string to _OSI support).
Maybe this another output could help you:
Quoted 7 lines
$ cat /sys/bus/acpi/devices/INT33C5\:00/status
0
$ cat /sys/bus/acpi/devices/INT33C5\:00/power_state
(unknown)
Device INT33C5 is in that dmesg log:
acpi INT33C5:00: Cannot transition to non-D0 state from D3
The appended patch should make these messages go away, please test.
Quoted 2 lines
And status 0 in sysnode could indicate that acpi device is not present right?
That's correct.

Hello Rafael,

sorry for long delay. Now I tested your patch on top of 4.0-rc6 version and I'm still getting one acpi error message (and lot of others) in dmesg each time I open LID of my laptop:

kernel: [ 62.016803] acpi device:41: Cannot transition to power
state D3cold for parent in (unknown)

If it helps here is more info about that acpi "device:41":

/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/INT33C6:00/device:41

$ grep "" *
adr:0x00000001
path:\_SB_.PCI0.SDHC.WI01
power_state:D0
status:15

And here about parent ("../")

/sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/INT33C6:00

$ grep "" *
adr:0x00170000
hid:INT33C6
modalias:acpi:INT33C6:PNP0D40:
path:\_SB_.PCI0.SDHC
status:0
uevent:MODALIAS=acpi:INT33C6:PNP0D40:
uid:1

It is OK, that one device has status 0 (not present) and its child has non zero status? Looks like here is problem...
