Bug 6058

Did it (S3) ever work before? If yes, can you please identify which version 
breaks it? Thanks!

Not that I am aware of, I have only used 2.6.12 and 2.6.15 kernels on this
machine. So it's possible that it has worked before, but I am unable to say for
sure.

Does this mean it is unlikely to get fixed, or?

Do you need any more information other than what I have provided? I am happy to
do anything that may be required.

Did you use wireless? Somebody said wireless configuration will break s3. If 
you have, please try unload wireless driver.

I've looked into this in the past. By testing with a serial console, we were
able to get an nc4000 (almost identical to the 4010 - same chipset) to resume if
we did so *immediately* after a suspend, but there was evidence of memory
corruption - the kernel would tend to crash in odd ways. The longer the period
of time between suspend and resume, the less likely a resume attempt was to
succeed. The obvious suggestion was that the RAM wasn't being put into
self-refresh mode, but there's no documentation available from ATI.

Can anyone please tell me what the status of this bug is?

Unresolved.

A lot of suspend-related changes have gone in since the last September.  Have anyone checked if that issue is still present or if the symptoms have changed?

Please re-open if this is still a problem in linux-2.6.22.stable or later.

Using 2.6.22.12-0.1-default in an opensuse distribution, I can confirm that this does not work on a nc4010.  Using the s2ram utility with the f flag and various combination of other flags always resulted in a black screen during resume and blinking num-lock and caps-lock lights.

I just tested, and this is true in 2.6.20 and 2.6.22 on Ubuntu Feisty and Ubuntu Gutsy. With S3_bios, the numlock doesn't flash. With S3_Mode, it does.

tarek : )

Tarek,
Your laptop probably has a different issue.
Please open another bug report and attach the dmesg, acpidump and /proc/interrupts.

Since this is the only bug I found for this model, I'll give it a go. I've compiled 2.6.29-rc5 to see if it wakes (after these long years of resisting) but it still doesn't. The symptoms are the same as in the first post (running fresh install of Debian Lenny).

It works without problems on WinXP.

So what should I provide now?

*** Bug 12773 has been marked as a duplicate of this bug. ***

Hi, Aljaz
    Will you please add the boot option of "acpi_sleep=old_ordering" and do the following test?
    a. dmesg > dmesg_before; echo mem > /sys/power/state; dmesg >dmesg_after; sync; reboot;
    b. press the power button and see whether the box can be resumed.

    If it can't be resumed, please reboot the box and see whether there exists the file of dmesg_after.
    
    It will be great if you don't add the boot option of "acpi_sleep=old_ordering" and do the same test(step a & b).
    Thanks.

aoo suffix stands for the acpi_sleep=old_ordering

I did so. Both times the computer didn't wake, but the vent was up which I don't remember before. The keyboard didn't respond, hard reset did. Without acpi option (normal boot) both caps lock and num lock after a while of waking up started flashing. That's the only difference between both cases.

Hi, Aljaz
    Thanks for the test.
    From the log in comment #15 it seems that the box can be resumed from S3. But the remaing issue is that:
    a. keyboard can't be used if the acpi_sleep=old_ordering is added. But it can be used without acpi boot option
    b. the screen remains black (This should be related with ATI graphicis driver).
    
Does any ATI guy look at this issue? The box can be resumed but there is no screen after resume.

   Thanks.

try the custom DSDT

Hi, 
   It seems that there exists the following warning message after suspend/resume.
   >ACPI Error (psargs-0359): [_ksy] Namespace lookup failure, AE_NOT_FOUND
   It is very interesting.
   But from the ACPIdump we know that no _ksy object is called in the object of \_TZ_.C1F3._STA
   
    Will you please try the custom DSDT and do the test as mentioned in comment #14?(The boot option of "acpi_sleep=old_ordering" is not needed).
    How to use the custom DSDT can be found in (http://www.lesswatts.org/projects/acpi/faq.php)
   Thanks.

Problems:
1) I cannot compile the iasl tool:

42: undefined reference to `AcpiGbl_GlobalList'
/home/aljaz/temp/acpica-unix-20090320/tools/acpiexec/../../utilities/uttrack.c:242: undefined reference to `AcpiGbl_GlobalList'

collect2: ld returned 1 exit status
make: *** [acpiexec] Error 1

2) with the debian lenny version I get this:
~/temp$ sudo acpidump > acpidump.out
~/temp$ sudo acpixtract DSDT acpidump > DSDT.dat
~/temp$ sudo iasl -d DSDT.dat

Hi, Aljaz
    Sorry that I don't make it very clear about how to use the custom DSDT.
    In fact the file of DSDT.hex is attached. In such case the previous four steps can be skipped. You can start from the step 5.
    Thanks.

before message with custom dsdt

Now it's even weirder. I compiled now the released kernel with the custom DSDT and there is no after message anymore. The computer goes to sleep but never wakes up. The disk won't even bother to wake nor the fans as before. I tried it several times. After a while of waking up the num and caps lock leds start to flash but not everytime.
I'm only attaching the before message.
I tried with or without gdm running.

Hi, Aljaz
    The test results seems weird. Before the custom DSDT is used, the box can be resumed from S3(in comment #15). But after using the custom DSDT, the box can't be resumed any more.

    From the test log it seems that the custom DSDT is tried on the 2.6.29-stable kernel. Right?
    Will you please try the custom DSDT on the 2.6.29-rc6 kernel?  It will be great if you can confirm whether the box can be resumed from S3 on the 2.6.29-rc6 kernel again.
    Thanks.

dmesg before without X

Adding 3 attachments:
- 2 of before and after when X was stopped
- just one "before" when X was running

This was now on 2.6.29-rc6 with the attached DSDT.

Created attachment 20692 [details]
dmesg after without X

Created attachment 20693 [details]
dmesg before with X

In the scenario when there was an "after" file, there was nothing happening during wake-up but after a while both caps and num lock started flashing.

Hi, Aljaz
    Thanks for the test.
    It seems that the box can be resumed on the 2.6.29-rc6 kernel after using the custom DSDT. 
    And after the custom DSDT is used, the following message won't be complained again:
    >ACPI Error (psargs-0359): [_ksy] Namespace lookup failure, AE_NOT_FOUND
    >ACPI Error (psparse-0537): Method parse/execution failed [\_TZ_.C1F3._STA] (Node f7017348), AE_NOT_FOUND

    It seems that the content of DSDT table is changed by BIOS in course of suspend/resume, which causes that some ACPI objects can't be evaluated correctly.(When the custom DSDT is used, its content is in the kernel meory region. And it won't be changed by BIOS).

    Will you please do the following test on the 2.6.29-rc6 kernel and confirm whether the content of DSDT table is changed by BIOS? 
    a. acpidump >acpidump_before; 
    c. echo mem > /sys/power/state; acpidump >acpidump_after; dmesg >dmesg_after; sync;
    d. press the power button and reboot the system.
    e. after the box is rebooted, please attach the output of acpidump_before/after.

     thanks.

acpidump after

I have struggled now to get to this after file, since it needed quite some reboots to finally get one. It seems that every sleep try is somewhat a new experince.
I have also done the same with the non-dsts kernel and the result seems to be the same - both files are, according to meld (file compare tool) identical.
This indeed seems to be a very weird piece of hardware.

Hi, Aljas
    Thanks for the test. The test result is weird. The content of DSDT table is not changed in the course of suspned/resume. 
    From the log in comment #15 it seems that there exists the following warning message:
   >ACPI Error (psargs-0359): [_ksy] Namespace lookup failure, AE_NOT_FOUND
   >ACPI Error (psparse-0537): Method parse/execution failed [\_TZ_.C1F3._STA] (Node f7017348), AE_NOT_FOUND

    But from the acpidump we know that no _ksy object will be called in the \_TZ.C1F3._STA. 
   >PowerResource (C1F3, 0x00, 0x0000)
        {
            Method (_STA, 0, NotSerialized)
            {
                Return (C1EB (0x02, 0xA0))
            }
   
    If so, the above message is caused by that the content of DSDT table is changed. But unfortunately there is no change in the DSDT table. 

    At the same time when the custom DSDT is used, there is no above warning message.
    Now I can't understand why this happens.

dmesg after - no X, BT&Wireless off

This time I tried stock Debian Lenny kernel (2.6.26-something) and it produced a bit more info on wake-up. I hope it's more helpful than previous attempts.

ACPI dumps remain the same before and after in this case as well (also the same under vanilla 2.6.29 kernel).

Aljaz,

How long are you leaving the system before resuming? My experiments with an nc4010 in the past suggested that the memory self refresh wasn't being enabled, leading to memory corruption and the system only resuming if tested within a few seconds of suspend. If that's the case, can you try leaving the machine for longer and check that you get the same results as you've already posted?

Even worse. I tried now the same exercise with all the kernels and the result was the same after 3-5 minute pause: no after files at all! This consistent behaviour didn't happen before where I got to an after file here and there.

It's really strange since suspend and wake work flawlessly under windows xp regardless of the pause in between.

Hi all. Sorry for my english at first. My new HP HDX18 laptop doesn't wake up to. After resume it can't find any hard drives. This can be reproduced in all kernels and distributions, what i try (ubuntu 8.10 (amd64, x86), Gentoo 2008 (x86_64), Fedora 10 (x86, x86_64)). All distributions have 2.6.27 kernel. On Gentoo i try kernel 2.6.29 - nothing change. When i try to boot from usb hdd and get all kernel logs. Here they are: http://unitedchat.ru/pub/hwinfo_and_logs.tar.gz .
If need more info - contact me, please dsyabitov at gmail.com

Ooops. Sorry, i'ts my mistake with many tabs opened.

Hi, Damir
    It seems that your box is different with Aljas's. Maybe it is a different bug.
    Will you please try the latest kernel and see whether the issue still exists? If it exists, please open a new bug and attach the output of acpidump, lspci -vxxx.
    Thanks.

Hi, Aljaz
    Sorry for the late response.
    From the comment #33 it seems that there is no file of dmesg_after. 
    Will you please double check it again?

Thanks.

With what kernel version (currently running 2.6.30.1)?

Hi, ykzhao! It was my mistake posting here - it's 12276 bug and now it fixed (by updating bios).

it will be better if you can try the 2.6.31-rc3 kernel or the latest linus git tree.
Thanks.

acpi before's with 2.6.31 rc3 kernel

No, no changes. It goes into sleep, then when I turn it on it just suspiciously silent, disk spins after a while but the vent and display are not in action. I have to power boot to start again and I have no after files again this time.

File's legend:
- no suffix: 2.6.31 rc3 normal kernel
- DSDT:      2.6.31 rc3 custom dsdt kernel
- DSDT2:     2.6.31 rc3 custom dsdt kernel with BT/wireless turned off.

GDM was stopped before trying in all three cases.

Hi, Aljaz
    Thanks for the test.
    From the test in comment #41 it seems that there is no file of dmesg_after, which indicates that it is not resumed. But from the test in comment #24/31 it seems that the box can be resumed from S3. It is weird.
    Will you please enable "CONFIG_PM_DEBUG" in kernel configuration and do the following test?
    a. kill the process using /proc/acpi/event (use the command of "lsof /proc/acpi/event" to get the process ID)
    b. echo devices > /sys/power/pm_test
    c. echo mem > /sys/power/state; dmesg >dmesg_after_device
    d. wait for five seconds and see whether it can be resumed.
    e. If it can be resumed, please echo "platform/cpu/core" > /sys/power/pm_test on by one and repeat the step c/d.

   Thanks.

Yukai,

whether or not the system resumes will typically depend on how long it's suspended for. An immediate resume may result in a dmesg_out. As noted in comment 4, it seems as if the memory becomes corrupted over time.

thanks for pointing out this issue.
If so, we have no way to fix this issue unless no document is available from ATI.

Suspend/resume can work well on windows XP. Maybe the memory refresh mode is handled correctly on windows XP. 

Thanks.
