Desktop and S3 suspend the Holy Grail of ACPI?

Desktop and S3 suspend the Holy Grail of ACPI?

[nick]

I am new to ACPI but I have searched the archives, looked at the MAN 
pages used Google to the best of
my abilities and I still have some questions about ACPI. My basic goal 
is to be able
to suspend my desktop machine to S3 when not in use. I need to use the
machine several times throughout the day, and feel it is a waste to leave
it on continuously. The system spec are: Intel D875PBZ, Intel P4 3GHZ,
Radeonm 9700 pro, Sounblaster Live, Debian unstable with 2.4.23 and
2.6.2 kernels available, both with ACPI compiled as modules. Pressing
the power button once gracefully shuts down the machine running either 
kernel.

After reading the documentation, I am still not sure how to try to
suspend to S3. Is there anyone with this motherboard succesfully using
S3 suspend? Is it reliable and stable, suspend after suspend.
Is S3 suspend with Linux on the desktop the Holy Grail of ACPI? The
machines suspends to S3 in Windows 2000 Pro, also shuts all the fans
down too, totally silent.

Any advice would be appreciated.
Can anyone recommend any Pentium 3/4 desktop motherboard that will S3 
reliably in Linux?

If this is not possible yet, are there any other Linux hardware problems 
where S3 works reliably?

Nick

There is at least one problem for which I don't think that you will have
S3 working even in the near future.
You do have a radeon 9700 and due to lack of supports by ATI those days,
I don't see how a developper can include power management codes in any
drivers other than by a cycle of guess, then try and guess again what
happens on errors.
Note that S3 may work though if you do not have AGPGART compiled,
and you do not use any kind of binary-only drm drivers from ATI.

Would an older ATI card, like a Rage 128 Pro or original Radeon (7000 I
believe) work?

I've got a laptop running Fedora Core 2 out of the box, and all I do is

# echo 3 >/proc/acpi/sleep
and I use the power button to wake it up.

I've also got a D875PBZ, however

[root-BJIgRQarj28@public.gmane.org /]# echo -n 3 >/proc/acpi/sleep
Stopping tasks: ==============================
 stopping tasks failed (1 tasks remaining)
Restarting tasks...<6> Strange, katad-1 not stopped
 done
[root-BJIgRQarj28@public.gmane.org /]#

which I guess is due to its SATA boot drive.
Do you have a regular PATA drive?

cheers,
-Len

Yes.  The radeon 7000 should be ok, and to be fair for ATI, they have
rewritten and given back the portion for this on the new radeon frame
buffer.

Yes I do have regular PATA drives. Could you give me the details on your 
configuration? Other hardware, kernel and patches applied?

Thanks.

On this box S1 works for me, but S3 doesn't resume (below)

Note that you need to enable S3 in the BIOS SETUP to try S3.

Note that neither S1 nor S3 will do anything on the SMP kernel.
(and unfortunately, they will not even tell you that when you try)

here a bunch of garbled junk comes out my serial console.
But video is not restored to my matrox mystique FB.
ping doesn't work.

Curiously CTRL-ALT-DEL results in the following on the serial console:

quotaoff: numerical sysctl 5 16 8 is obsolete.
md: stopping all md devices.
md: md0 switched to read-only mode.
Restarting system.

<and the system reboots here>

So it seems that the system did resume and talk to the keyboard at
least...

You can enable S1/S3 with SMP with the "noirqbalance" boot parameter (to
disable kirqd which refuses to die during suspend) and this patch:

As far as i know, software suspend/resume support for SMP haven't been
done right now.

Try getting suspend-to-disk working, first.

I do have S3 enabled in the BIOS. I just grabbed Debian's 
kernel-source-2.6.3 and compiled it without SMP support. cat 
/sys/power/state gives me standby mem disk.
I tried echo -n disk /sys/power/state (as per the ACPI docs on 
sourceforge) and the system did try to write the contents to disk, but 
failed. I then realized I don't have enough swap space, which I will try 
to exapnd later.

I then tried eco -n mem > /sys/power/state and the machine basically 
shuts down (completely off I think) so fast that I don't get a chance to 
see any console messages. Doesn't resume when I hit a key. If I try to 
hit the power button once, the machine beeps hi-lo (BIOS error I guess?) 
without booting. I have to then hold the power swithc for 4 seconds, 
then turn it on again.

Doing:
# /etc/init.d/acpid stop
echo -n standby > /sys/power/state
the machine does go into standy with no error messages.
I am able to resume by hitting the power button once.

Thank you for the  "acpid stop" tip, I never saw it mentioned in the howto.
The only problem is the case fans are still on even though I have the 
fans set for off at low temperature in the BIOS.
I was hoping for a silent sleeping machine; maybe I'll wait an hour and 
see if the case fans do eventually shut off.

This is on the INTEL D875PBZ, is that correct? What kernel version is 
FC2-test1 UP kernel? I am also assuming debian's kernel 2.6.3 would have 
all the latest ACPI patches?

a better alternative to S3?

I tried playing with suspend to disk in kernel 2.6.3. It was a no go. I 
have highmem enabled on this machine which has 1 gig of RAM.
Going to try pmdisk.

I mean that swsusp is easier to make going than S3, and it is quite
usefull to know if it works for you. If it does not, its unlikely that
S3 will.

Forget pmdisk, that will not work anyway. Try running without highmem
(at least for a test).

Why shouting and 3x"?"?

It should work with preemption, but preemptive kernel is slightly
harder than usual. If he wants to get it to work, it is best to
disable preemption.

Pavel, I'm having some trouble understanding the swsusp.txt file. It 
states: " You must explicitly specify the swap partition to resume from with
``resume='' kernel option."

my swap partition resides in /dev/hda4

So I think  I need to do something like this?
# Boot up Linux by default.
#
default=Linux

image=/vmlinuz
        label=Linux
        read-only
append="hda=autotune resume=/dev/hda4"   <---- added this
#       restricted
#       alias=1

image=/vmlinuz.old
        label=LinuxOld
        read-only
append="ide0=ata100 hda=autotune"      
        optional
#       restricted
#       alias=2


image=/2.4.23
        label=2.4.23
        read-only
        optional


Is this correct, or do i pass the resume option at boot time as a LILO 
option?

Nick

Then it should automatically resume next time the power button is 
pressed, no other options need to be passed at the LILO prompt?

Ok, it seems to work with a 2.6.3 kernel; highmem and preemtion disabled.
Can I ask you how you have USB enabled? Compiled into the kernel or as 
modules?
I could have sworn I erad something about ACPI swsusp and USB conflicts.

Do you use swsusp constantly, and do you find reliable so far?

Hmm.. Sorry.. I just reread your subject line.. It 
says.. S3 suspend.I've not been able to get that to work. 
(Still have not experimented a lot) and Yes.. you heard
right.

Currently Have got S4 to work.. Suspend to disk. I think it's also 
swsusp. (or swap suspend)

Refer to my thread "success: S4 on D600" or somethinglike that.

USB/eth is modules. rmmod the eth mod before S4'ing.
S3/S1 hangs on resume. Hangs as in Console/X/graphics.

I suspend only a few times.. Just got it working like On Sunday.
and today's Tuesday.. :)

As a test I suspened the machine twice; each time the machine was off 
for approximately 5 minutes. It resumed twice without any problems (into 
X with a mozilla and xmms)
As another test, I opned up a few apps in different workspaces: abiword 
with a document, mozilla browser and mail, xmms playing an internet 
stream. I then suspended in hopes of resuming the next day after school. 
After about 14hrs I tried to resume, and everything seemed fine, excpet 
my USB mouse was unrespnsive. I was able to brinx X down into a working 
console, startx again, but still no mouse.

In debian kernel 2.6.3 I have the NIC and USB options compiled in. 
Should these be modules that are removed before swsusp?
There's aslo mention of a swsusp script, but was unable to find one in 
../Documentation/power or via apt-cache search; I'm assuming that I need 
this script, which will remove the modules before swsusp and modprobe 
them after resume.

Thank you for your time and patience.

You should not need any script; but it probably has better chance
working with USB modules removed. Anyway that's a bug in USB support,
ask on USB list.

OK, heres what works so far on plain vanilla 2.6.3 with 2.6.3 acpi patch 
applied; smp ans preemption disabled, eth0 e1000 and usb as modules.

S1 goes into standyby, after issuing /etc/init.d/acpi stop, but the fans 
stay on (as they also do in Win2k when standby is set to S1 in bios); 
seems to reliably resume, but it's too niosy for a computer that is 
essentialy in the bedroom.

S4 works , but I have to unload the USB modules buy hand ( I also unload 
eth0 e1000 to be safe) and modprobe them after resume. Resume takes a 
little longer than a normal boot up, but it saves me time insofar as 
opening the applications I comonly use.

Still no S3, which is what I'm really gunning for; either echo -n mem > 
/sys/power/state or echo 3 > /proc/acpi/sleep now results in the machine 
locking up after a series of messages,
something to the effect of: resuming from /dev/hda4
                                           Resuming from device hda4
                                           Resume Machine: This is 
normal swap
                                           ACPI: (supports S0 S1 S3 S4 S5)
                                           Stopping tasks: 
==========================|
                                           hdd: start_power_step (step.o)
 and a few more lines concerning hdd and hdc, I had to copy all this 
down on pen and paper.

A couple of things I noticed, with the Debian 2.6.3 kernel trying to S3 
resulted in a shutdown, now with ACPI patch and vanilla 2.6.3, it hangs 
and results in said messages. S4 takes takes more than couple of minutes 
longer to compete with the vanillas kernel, I thought the machine locked 
up, but decided to wait a few more minutes, and it seemed to finish the 
swsusp.
I did see a few messages relating to "Badness" but didn't get a chance 
to write them down.

So if there's anything you guys -- who have been more than helpful btw 
-- would like me to try as far as getting S3 functional, I'm all ears. 
I'm also assuming I need some kind of script for S4 to unload the USB 
and NIC modules, stop acpid, then revers all that upon resume. Is this 
something I'm going to have to write myself?

Thanks in advance.

Thats was a typo, the Debian kernel is faster, and the vanilla kernel w/ 
acpi 2.6.3 patch takes significantly longer to finish the swsusp, but it 
does finish it.

Well, ideally you should not workaround e1000/usb problems with
scripts, but add driver model support to both of those.

You may want to try S3 with those two modules unloaded. There's some
chance it resumes with video not working (you can tell by typing find
/ -- if hdd starts flashing, machine is okay but no video).

It was a no-go with S3. The machine just shuts down.

Is anybody aware of any Intel or Intel chip based (p3 or p4)
motherboards where S3 works reliably?
