Description Bruno Jacquet 2010-04-12 17:17:22 UTC
Hi, Since I'm on the 2.6.33 kernel My PS/2 keyboard (and mouse when I use an adaptater USB to PS/2) don't get powered off when I shut down my PC. NumLock light and the red light of my mouse are still here. USB has no problem. I'm using the 2.6.33 kernel on an x86_64 CPU. My motherboard is an Asus M2N-E. I thought it was a problem of configuration so I opened a bug report on the ArchLinux bugzilla but they told me to report it here. If you need more infos or experimentations, ask. Thanks. Bye
Comment 1 Len Brown 2010-04-13 01:52:39 UTC
the lights went out on 2.6.32 and stopped going out using 2.6.33? Please show the output from "cat /proc/acpi/wakeup" for the old and new kernels.
Comment 2 Bruno Jacquet 2010-04-13 11:19:29 UTC
I don't have the 2.6.32 installed right now but I think it started when I switched to 2.6.33. I have another kernel installed : 220.127.116.11, with this one, no problem, lights go out (all of the 3 LED blink then all shut doww with previous kernels, with 2.6.33 there's no blink, it just stays with NumLock on and nothing happens) If you want me to reinstall a 2.6.32 I can. Here are my results for /proc/acpi/wakeup : Device S-state Status Sysfs node HUB0 S5 disabled pci:0000:00:06.0 XVR0 S5 disabled pci:0000:00:0f.0 XVR1 S5 disabled XVR2 S5 disabled XVR3 S5 disabled XVR4 S5 disabled XVR5 S5 disabled UAR1 S5 disabled pnp:00:08 PS2K S4 disabled pnp:00:0a USB0 S4 disabled pci:0000:00:02.0 USB2 S4 disabled pci:0000:00:02.1 AZAD S5 disabled pci:0000:00:06.1 MMAC S5 disabled pci:0000:00:08.0 Both 2.6.27 and 2.6.33 gave the same output ( I diffed them ) Could it be a kernel .config in ACPI section problem ? (I've tried to find an option about shutdown of peripherals but didn't find any)
Comment 3 Dmitry Torokhov 2010-04-13 16:57:22 UTC
In 2.6.33 input switched from full reset to "light" reset for keyboards and mice. During full reset of the keyboard LEDs blink and then are turned off automatically, "light" reset does not do that. However the fact that LEDs on keyboard are turned off does not prove that we powered off PS/2 ports...
Comment 4 Bruno Jacquet 2010-04-14 11:48:57 UTC
It looks like you're right Dmitry. With 2.6.27 (that I thought was successfully shutting down my keyboard), LEDs are reinitialized and then none are glowing but if I plug my USB (converted to PS/2) mouse, the light on it is still glowing... So even with 2.6.27 my PS/2 peripherals are still powered. So where can the problem be ? Is it really a kernel bug ? Or a BIOS configuration ? Or even a Motherboard/Alimentation hardware problem ?
Comment 5 Dmitry Torokhov 2010-04-14 16:12:53 UTC
I _think_ that we should be powering off PS/2 ports unless they are configured as wakeup sources, but I'll let Len to decide...
Comment 6 Bruno Jacquet 2010-04-14 18:58:30 UTC
In my bios configuration, I have : Power on by PS/2 Mouse -> [Disabled] Power on by PS/2 Keyboard -> [Disabled]

Comment 8 Zhang Rui 2010-05-20 06:51:42 UTC
please attach the output of "grep . /sys/bus/*/devices/*/power/wakeup"
Comment 9 Bruno Jacquet 2010-05-20 19:45:47 UTC
grep . /sys/bus/*/devices/*/power/wakeup: /sys/bus/pci/devices/0000:00:01.1/power/wakeup:disabled /sys/bus/pci/devices/0000:00:02.0/power/wakeup:disabled /sys/bus/pci/devices/0000:00:02.1/power/wakeup:disabled /sys/bus/pci/devices/0000:00:06.0/power/wakeup:disabled /sys/bus/pci/devices/0000:00:06.1/power/wakeup:disabled /sys/bus/pci/devices/0000:00:08.0/power/wakeup:enabled /sys/bus/pci/devices/0000:00:0f.0/power/wakeup:disabled /sys/bus/pnp/devices/00:05/power/wakeup:enabled /sys/bus/pnp/devices/00:08/power/wakeup:disabled /sys/bus/pnp/devices/00:0a/power/wakeup:enabled /sys/bus/usb/devices/2-4/power/wakeup:enabled /sys/bus/usb/devices/usb1/power/wakeup:enabled /sys/bus/usb/devices/usb2/power/wakeup:enabled Note that I am now using a 2.6.34 kernel.
Comment 10 Zhang Rui 2010-05-21 01:12:29 UTC
please try "echo disabled > /sys/bus/pnp/devices/00:0a/power/wakeup" and see if the problem still exists.
Comment 11 Zhang Rui 2010-05-21 01:36:16 UTC
in /proc/acpi/wakeup: PS2K S4 disabled pnp:00:0a in sysfs: /sys/bus/pnp/devices/00:0a/power/wakeup:enabled this seems to be a problem, I'll look at the code first and update my findings later.
Comment 12 Bruno Jacquet 2010-05-21 13:16:15 UTC
I did and the problem still exists. I even tried to disable all the devices. Thanks for your implication ;)
Comment 13 Len Brown 2010-07-13 02:10:38 UTC
per comment #4, clearing the "regression" flag > In my bios configuration, I have : > Power on by PS/2 Mouse -> [Disabled] > Power on by PS/2 Keyboard -> [Disabled] Hmm, then perhaps Linux is doing something wrong... I would think we'd D3 these devices on a proper shutdown... please provide the output from acpidump
Comment 15 aceman 2010-08-07 12:20:12 UTC
Not fixed in 2.6.35.
Comment 16 aceman 2010-10-23 16:08:47 UTC
I also have an ASUS motherboard (M2N68) - AM2+ based. The original reporter also mentions a x86_64 CPU. Maybe there is a common BIOS/ACPI problem on these boards?
Comment 17 Bruno Jacquet 2010-10-26 22:02:48 UTC
Issue still present in 2.6.36 Regarding what aceman told, could it be the DSDT or something similar ? (I have no clue, just suggesting)
Comment 18 Bruno Jacquet 2011-01-08 17:31:24 UTC
Not fixed in 2.6.37
Comment 19 Zhang Rui 2012-01-18 02:02:55 UTC
It's great that kernel bugzilla is back. can you please verify if the problem still exists in the latest upstream kernel?
Comment 20 Bruno Jacquet 2012-01-19 22:07:21 UTC
Yes, the bug is still in 3.2
Comment 21 aceman 2012-02-08 17:51:32 UTC
Confirming, still exists.
Comment 22 Lan Tianyu 2013-04-03 01:30:12 UTC
Sorry, please check again whether the problem still exists in the latest kernel (v3.9-rc5). From your comments, there is no problem when use usb mouse and keyboard, right?
Comment 23 aceman 2013-04-07 13:45:18 UTC
The problem still exists in 3.8. I do not have USB keyboard, but the original reported seems to say USB is fine. We both report the problem is on PS/2.
Comment 24 Lan Tianyu 2013-04-07 14:02:03 UTC
How about these device status after cool shut down and not boot up?
Comment 25 aceman 2013-04-07 14:28:48 UTC
What do you mean? The computer is completely shut down but the Num lock keyboard LED still glows. Of course the computer is still plugged to the mains and devides that charge through USB ports get power.
Comment 26 Lan Tianyu 2013-04-08 03:48:33 UTC
(In reply to comment #25) > What do you mean? I mean power off the machine > The computer is completely shut down but the Num lock keyboard LED still > glows. > Of course the computer is still plugged to the mains and devices that charge > through USB ports get power. How about cut the power (unplugged to the mains) and then repower the machine but not boot? What's these devices state? From the acpi table on this machine, there is no power resource for PS2K and PS2M. This means linux ACPI can't power off these devices.
Comment 27 Bruno Jacquet 2013-04-08 07:24:57 UTC
Cut power (for at least 1 min or capacitors remain charged and it is not relevant I guess) and then replug power but no boot : LED stay off. Windows can bring these devices off, would it be some kind of broken ACPI table as usual?
Comment 28 Lan Tianyu 2013-04-08 08:41:05 UTC
I have no idea how windows does it. Do you have a usb keyboard and mouse? If yes, Can you try to unload these device driver and check these devices's state? Or not load drivers after boot up and check devices' states again?
Comment 29 Lan Tianyu 2013-05-27 14:03:49 UTC
Comment 30 Lan Tianyu 2013-06-03 07:00:20 UTC
Since no response for a long time, close this bug as will_fix_later.
Comment 31 aceman 2013-06-03 19:58:17 UTC
What response did you expect? What kind of bug closure is this? Is the bug fixed now?
Comment 34 Lan Tianyu 2013-08-06 02:52:47 UTC
Sorry, for later response. Currently, I have no good idea and hope some PS/2 expert can help.
Comment 35 Patryk Rządziński 2014-03-26 10:44:40 UTC
Hello, I'm actually having the same problem. I've just switched to a new keyboard which is ps/2 in turn (previously had usb keyboard and there was no problem). I have no wake-on-* enabled in bios. I have also no suspend/resume functionality compiled into the kernel. My system is: 3.10.33 #2 SMP PREEMPT Tue Mar 25 10:58:35 CET 2014 x86_64 Can I help with any debug info?
