Odd thing I noticed, it works fine at the GDM prompt, however, once I login, it gets the strange behaviour.

I tentatively reassigned this to acpi.

Breaks for me whether I close the lid or use pm-suspend from command line or use the keyboard hotkey.

acpidump-gary

for me, works heyboard hotkey and also pm-suspend (latest version, I use Archlinux 64-bit) fine, not work lid only

Alois, are you sure you're having the same problem as me?  My system just hangs.. I can't switch to console or anything.

Gary, i think, that yes. I must min. 2x shutdown laptop.
Can you say, version o X-server, pm-utils, and have you some errors in /var/log/errors.log ?

try the debug patch

Do someone have an opportunity to try the patch on the latest kernel and see whether the following message is complained?
   > PM: Device PNP0C0D:00 failed to resume: error 1

Thanks.

Hi, Alois
    It seems that your issue on your box is different with that on Gary's one. The screen is blank when the LID is used to suspend/resume, right?
    If so, will you please try the following patch on the latest kernel and see whether it works for you?
    >http://lists.freedesktop.org/archives/intel-gfx/2009-December/005143.html

Thanks.

Hi, Gary
    Will you please boot the system with the boot option of "drm.debug=0x06 printk.time=1" and test whether the system can be suspened/resumed several times under the console mode? Please do the following test:
    1. kill the process who uses the /proc/acpi/event(use the command of "lsof /proc/acpi/event" to get the process)
    2. dmesg >dmesg_before; echo mem > /sys/power/state; dmesg >dmesg_after;
    3. after the system enters the system, please press the power button and see whether the system can be resumed.
    4. if the system can be resumed, please repeat the step 2/3 several times.
    
When it fails to be resumed, please reboot the system and attach the output of dmesg_before/dmesg_after?

Thanks.
    Yakui.

I will test it soon, but it seems you're expecting different symptoms.  My system never fails to resume.  It hangs before actually suspending during suspend.  Should I still do the same process?  Also, it's fine in console only mode, the problem occurs only once I've logged in through gdm.

I patched with this patch kernel 2.6.32.1 and i see not error in /var/errors.log. I think, this patch works.

I think yet also, very sorry to bring my report of another bug to report other bug.

That's Alois's issue that got solved, not mine.  I still can't suspend in 2.6.33-rc1.

To reproduce the behavior, I have to be logged in to my X desktop, but then I can switch over to virtual terminal.  Is this ok?  I will perform the test soon.

Gary,
Please try with and without CONFIG_DRM_I915_KMS

this looks like a graphics problem to me.
re-assign to Yakui.

Hi, Gary
    Will you please boot the system into console mode with KMS enabled and do the following test?
    1. kill the process using /proc/acpi/event(use the command of "lsof /proc/acpi/event" to get the process id)
    2.  echo mem > /sys/power/state; dmesg >dmesg_after1
    3. wait for one minute and then press the power button to see whether the box can be resumed.
    4. If it can be resumed, please "echo mem > /sys/power/state; dmesg >dmesg_after2"
    5. wait for one minute and then press button to see whether the box can be resumed.

    If it can't be resumed, please reboot the box and see whether the file of dmesg_after2 is created.

    It will be great if you can boot the system into console mode with KMS disabled and do the above test again. (You can add the boot option of "nomodeset").

thanks.

Using KMS in console only mode:
Rebooted into single user mode with 2.6.33-rc1 from mainline ppa.
1. No processes using /proc/acpi/event
2. Works fine.

No KMS in console only mode:
Rebooted into single user mode.
1. No precesses using /proc/acpi/event
2. Will not resume from suspend, no dmesg files obviously.

Using KMS when logged in with X: 
1. Switched into VT for running the commands.
2. acpid kept creating new processes using /proc/acpi/event, did a 'service acpid stop' and that fixed it.
3. Works fine.
This confuses me.  Seems intermittent now when it wasn't before.  

After multiple reboots I was able to get it to fail consistently again.
Using KMS when logged in with X take 2: 
1. Killed acpid.
2. Suspended once ok, have dmesg from this.
2. Suspended second time fails.

happens in 2.6.33-rc2 as well

happens with ubuntu lucid alpha1 livecd running 2.6.32 as well, so it's probably not a configuration issue

Working on a git-bisect for this issue.

    writeback: switch to per-bdi threads for flushing data

    This gets rid of pdflush for bdi writeout and kupdated style cleaning.
    pdflush writeout suffers from lack of locality and also requires more
    threads to handle the same workload, since it has to work in a
    non-blocking fashion against each queue. This also introduces lumpy
    behaviour and potential request starvation, since pdflush can be starved
    for queue access if others are accessing it. A sample ffsb workload that
    does random writes to files is about 8% faster here on a simple SATA drive
    during the benchmark phase. File layout also seems a LOT more smooth in
    vmstat:

First-Bad-Commit : 03ba3782e8dcc5b0e1efe440d33084f066e38cae

Can you double check that HEAD at 03ba3782e8dcc5b0e1efe440d33084f066e38cae is definitely broken and HEAD at 66f3b8e2e103a0b93b945764d98e9ba46cb926dd definitely always works?

Are you using any special file systems?

03ba3782e8dcc5b0e1efe440d33084f066e38cae (a) is definitely broken in the same way as the releases I started with (2.6.32 rc1-final and 2.6.33 rc1-rc2).

66f3b8e2e103a0b93b945764d98e9ba46cb926dd (b) is good in the sense that I can suspend lots of times without a hang, but it is not stable.  My system will just hang after a minute or so of use.  Seems random.

still occurs with 2.6.33-rc4.  If I want to figure it out myself, what should I do?  I'm new at this, but I know C.  Can I just run a 2.6.32 kernel, and undo this commit, or is there going to be a lot more to it than that?

That would be a good start.

Depends on what you get when the bisected commit is reverted.

Hi guys!
I have the same issue on my HP 530 laptop. It freezes after two suspend/resume cycles. It hangs during third suspend - display is black, nothing works except hard power off. Kernels 2.6.32.x and 2.6.33-rc5 are affected. Tell me if I can help with testing or something else.

ha! maybe now they'll listen to me since I'm not the only one in the
world with this problem :-).  Can you give an lspci -v output so we
can compare hardware and try to figure it out?

I've created an attachment. By the way, with 2.6.32 kernel my laptop resumes from suspend only with black screen, but it was fixed somewhere in 2.6.32.x versions.

Very odd, there are not really any similarities.

Yours:

Intel Pro/100 Ethernet
intel 3945ABG wireless

Mine:
gm45 chipset, integrated graphics
realtek 1gb lan
atheros 2425 wireless

Are you running a 64-bit kernel?  I am. Haven't tried with a 32 yet.

My intel core duo doesn't support 64 bit, so I am running 32 bit only. Seems problem is in kernel.

maybe you could try a git bisect and see if we end up in the same
place?  It takes a while though to do all the recompiling..  I doubt
the validity of mine b/c it was intermittent once without explanation.

No problems, I can compile and check. But I'm not familiar with git, so it would be nice if you will give me bisected sources to compile. Or you can tell me the command to get bisected sources from git.

well, http://www.reactivated.net/weblog/archives/2006/01/using-git-bisect-to-find-buggy-kernel-patches/

but you have to recompile the kernel about 12 times this way.  It does
a binary search starting from first known good and first known bad.
You recompile, and then tell it if the current kernel is good or bad.

for instance, numbers 1 (good) out of 100 (bad)

it'll pick revision 50, you recompile, tell it bad.  It'll pick 25,
recompile, tell it good.  It'll pick 37.... until you find the first
bad commit.

Thanks for a good guide, I'll try to figure out bad commit, maybe today or on weekends.

Hi!
I was out of internet access for a while. I've found out, that bug has random nature. It can appear at any suspend, so it is very hard to detect a bad commit one. I've checked 2.6.33-rc7 - the bug is still here. Is there a way to get more information? Maybe some kind of trace or debug during the occur time? I will try to test git bisect much better.

Eureka!!

It only happens to me when I have an SD card inserted during suspend.  This leads me to believe the block layer commit during my bisect is indeed related.  Btw, just tested it on 2.6.33-rc8 and it still has the bad behavior.

I can suspend however many times I want.  If I insert an SD card, the next suspend will hang.

OK, then this is identical to an issue I'm currently discussing with Alan Stern. A solution is forth coming.

I've found, that my laptop hangs on suspend after using VirtualBox modules - even if I rmmod them.

I always use virtualbox, and it doesn't affect my issue... seems to be
a different problem?

Yeah, maybe. Since 2.6.32 I can't use virtualbox and switched to KVM.

what's the status?  I haven't tried to reproduce it since I figured out I could stop it by removing an SD card, but I'm noticing other people have the same problem.

Hi Gary!
Can you check if it is still a problem in 2.6.36?

Seems like it's no longer a problem in 2.6.36.

Ok, I will close this bug report. 

I don't think we will have any chance on finding something to backport to 2.6.32.y?  Maybe it's fixed already...
