Cannot resume from a suspend to ram on a Lenovo s10-3 using kernel 3.x

masmddr · 03-17-2012, 11:45 AM

Hello.

I have a Lenovo ideapad s10-3 running Arch Linux.
uname -r => 3.2.11-1-ARCH
kernel boot in /boot/grub/menu.lst => kernel /vmlinuz-linux root=/dev/disk/by-label/root quiet ro

This netbook always had a problem with resuming from suspend (pm-suspend), web search shows not just on Arch, but on kernel 2.6.x there was a solution, as stated in the Arch wiki:
https://wiki.archlinux.org/index.php..._.26_Hibernate

However since moved to kernel 3.x it stopped working again and adding nohpet to the kernel boot line doesn't work either.
The netbook suspends (all LED's go off and power LED blinks) but won't resume (Power LED is stable on, WiFi LED stays off, Screen stays off, HDD LED shows activity and then stays off).
I tried to suspend with music running in the background to see if it's just the screen staying off or something else, music doesn't resume either.

Like the wiki suggests, I have acpid running.
Searching the web I found a few suggestions but none worked:
adding nohpet acpi_osi=linux noapic acpi=off(refused to boot at all) to the boot line, tried all together and each by its own.

Tried to suspend using
pm-suspend --quirk-s3-bios --quirk-s3-mode, with the different boot options.

Tried suspending using
echo mem > /sys/power/state

Tried it all in init3 so it's not X11 driver's fault.

Any help would be highly appreciated.

Check your scripts in acpi or mebbe update pm-utils.

For a while in kernel 2.6.x there was an option for 'deprecated /proc/acpi files' in case you were running 'old software'. We all were - acpitools, and many scripts have not been updated. I looked into my box and /proc/acpi is not there in kernel 3.x and stuff is broken. Post the results of your enquiries - I have to update my own laptop :-D.

Thank you for replaying.

I'm not really sure what you mean...
I have acpid installed, not acpi since I don't find a use for acpi.
What is it about acpi scripts do I need to check?

/etc/acpi/handler.sh

Code:

#!/bin/sh
# Default acpi script that takes an entry for all actions

minspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq`
maxspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`
setspeed="/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"

set $*

case "$1" in
    button/power)
        #echo "PowerButton pressed!">/dev/tty5
        case "$2" in
            PBTN|PWRF)  logger "PowerButton pressed: $2" ;;
            *)          logger "ACPI action undefined: $2" ;;
        esac
        ;;
    button/sleep)
        case "$2" in
            SLPB|SBTN)   echo -n mem >/sys/power/state ;;

pm-utils version is pm-utils-1.4.1-4, I often update my system using pacman -Syu so it's usually up to date.
I had this problem for a long time but hadn't had the time / energy to deal with it.

Ok. Being technically precise, acpid is the executable I was referring to. acpi is a generally used term to apply to the business of necessary control, and not the executable or it's peculiarities in particular.
If you have that one great handler script, it usually needs tweaking.
In /etc/acpi/events the events your box responds to should exist. Here's mine: (Cleaned of crap)

Quote:

bash-4.1$ ls /etc/acpi/events
ac battery lidbtn powerbtn video_brightnessdown video_brightnessup videobtn

If you stop acpid, restart it with -l (Logging) and fiddle things like lidbtn, the events it sees will be displayed. Then you can put handlers in small pointers in /etc/acpi/events to the scripts in /etc/acpi. Grab fedora's or debian's scripts - they give you plenty to start with. Then fiddle them for your box to fix issues. Here's my suspend stuff (which works).
in /etc/acpi/events:

Quote:

# /etc/acpi/events/battery
# Called when AC power goes away and we switch to battery

event=battery
action=/etc/acpi/Decbattery.sh

My suspend script needs fixing - else I'll let xfce's power manager do it. XFCE's power manager uses Hal, and I always considered Hal the fast track to a home for the insane.

EDIT: Why not use pm-suspend & pm-hibernate if they are installed?

masmddr · 03-18-2012, 05:53 AM

Thanks for clarifying.

Code:

ls /etc/acpi/events
anything

cat /etc/acpi/events/anything 
# Pass all events to our one handler script
event=.*
action=/etc/acpi/handler.sh %e

So it basically catches all events, no?

Everything works, AC to battery, turning off screen when the lid if closed, battery % reporting, anything I can think of.
All except resuming from suspend.

I don't use pm-hibernate since I don't want to hibernate and never tried it, but I do use pm-suspend and it doesn't work.
I prefer it to work with xfce4's suspend, I have xfce4-power-manager installed.
But making it work via xfce comes after making it work at all :P
So far all and any way I tried to suspend, none worked. (I mean resuming never works, suspends fine)

business_kid · 03-18-2012, 10:12 AM

Ok then.

Have you tried

Quote:

sync; echo mem > /sys/power/state

My box works, but takes it's time entering suspend & hibernate.

masmddr · 03-18-2012, 10:48 AM

Tried it now, with and without the kernel boot options, also tried

Quote:

sync; pm-suspend

Suspends quickly, doesn't resume.

business_kid · 03-18-2012, 11:18 AM

It's probably a video thing. I would check that default script for a /propc/acpi reference.

masmddr · 03-18-2012, 11:58 AM

Thank you for your help.

I guess next time I buy a laptop, I'll make sure to do proper research about it before buying it.
Although many users report nohpet solves this issue.

This is beyond me and my understanding of computers, I give up :P

business_kid · 03-18-2012, 01:02 PM

If you're still stuck:
Essential information is logged to the dmesg buffer. You can faultfind from there. There is some command in the rc scripts

/bin/dmesg -s <buffer_size> > file

which stores the dmesg buffer. Pepper the rc scripts with it and see what you learn sending the different files to a usb disk

Explain exactly what happens and what doesn't during a resume. You press the power button (I presume), and . . .?

Also, What's your laptop? Some have notable quirks.

masmddr · 03-18-2012, 02:41 PM

Sorry, not sure what you mean with dmesg.

I suspend -> screen, fan, HDD, LED's all go out except the power LED which blinks.
I resume by either pressing any key or opening the lid -> fan,LED's,HDD goes on.
The HDD LED shows activity and then turns off, sometimes the wireless LED doesn't turn back on and the screen stays off without even back light.
If I suspend from a terminal then I should be back there when I resume (not set to lock on resume) but even if I blindly type any command, say reboot, it doesn't do anything.

I'm pretty sure it's not just the screen, if I had to guess I would say the screen stays off because something somewhere doesn't resume.

The laptop (netbook) is a Lenovo S10-3 (not S10-3t).
As far as I know it has issues with WiFi and resume under linux.
Both of the issues are fixable, except that the resume part doesn't work for me. (adding nohpet to kernel boot options)

business_kid · 03-19-2012, 04:32 AM

Lenovo is the sucessor to the IBM Thinkpad. They certainly had issues, and were a factor in abandoning apm code.( What worked other places didn't work there)

There are kernel fixes for them, and sites that specialise. I never owned one. If a Lenovo owner doesn't see this and chime in, try linux-laptop.net.

Thank you.
