Compaq Presario C700 series (C756CA) always freezes the second time when resuming from Suspend to RAM

[Kevin]

I have a Compaq Presario C756CA Laptop (which is in the C700 family), which has an Intel 3945 a/b/g wireless, Integrated Intel 3100 graphics chipset (using whatever free driver installs by default in Ubuntu), Samsung LCD display, "Syntek" Integrated Web-camera, Alps touch pad (running apparently with the synaptic driver), SATA 160 gb hdd, 2gb ram, Intel Core 2 Duo 1.6 ghz CPU. I have upgraded the firmware on the laptop to the latest, which I believe is F31 (released in March 2008).

Running Ubuntu 8.04 (Hardy), fully updated as of May 24, 2008. ( Linux 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux ). This problem "fails" out of the box. I also get the same behavior on Fedora 9 RTM out of the box.

Suspend to RAM works the first time. Resuming is fine, the first time.

Suspending to RAM a subsequent time completely freezes the machine. Can't switch to terminal window. Have to hard reboot (press and hold power or pull battery)

Hibernate works most of the time, although half of the time it comes back and says Hibernate failed (After I've already resumed from the hiberfile ;))

Symptoms on second resume: No video. No image. No LCD Backlight; I believe webcam cycles on and off once and hard drive accesses once, Caps lock key is NOT flashing (kernel doesnt seem to be panicking). Does not respond to terminal switches (ALT+F1, F2, F3, etc), makes no difference if X is running or not.

I have tried some of the HAL fixes on http://people.freedesktop.org/~hughsient/quirk/index.html . No success.
I have tried competely disabling everything USB using RMMOD, disabling my Intel 3945 wireless using both RMMOD and editing the suspend modules list, no success.

sudo pm-suspend adequately reproduces the problem, various --vesa options seem to make no difference, although I'm game to try a specific combo if someone has one that works for this config. I tried using the sleep.sh script in ubuntu, it produces the same behavior.

I will attach my HAL list, a DMESG report on first suspend, and a DMESG report on the second suspend (which requires a hard reboot), although I'm not sure that the second DMESG dump is "good".

[Kevin (linuxbugs-swiftninja)]

I forgot to mention that it looks in the DMESG dump like it might be the UVCVIDEO as well as the wireless, but it DOESNT * seem * to be because of either of them. I did an RMMOD on both (I only mentioned disabling the wireless in the original report), and it still died. Since UVCVIDEO magically restarts itself even though its module was removed, I killed the entire USB modules. At that point UVCVIDEO was definitely dead (webcam wouldnt restart), and problem STILL exhibits itself (still freezes on second resume)

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[rafaelj (rafaeljunqueira)]

I've tested the Alpha 5. I am newbie in linux so I can be sure, but I think that, unfortunately, the problem remains..
I have a Presario c700 (c770br) and have created (without the knowledge of this thread) a post on ubuntuforuns.com.

If you will, please, take a look:
http://ubuntuforums.org/showthread.php?p=5765977
Maybe it helps, who knows...

[rafaelj (rafaeljunqueira)]

Sorry, I mean "I am newbie in linux so I can't be sure"

[nola mike (abatzis)]

i've tried the new kernel, same problem. compaq c770--no webcam on mine, so that isn't the issue...

[Pieter Lenaerts (e-type)]

Indeed, same problem with 2.6.27-7-generic

any news on this? anyone on it?

[Andres Mujica (andres.mujica)]

Hi all, thanks for your bug report. In order to debug this we'll need more info.

Please read https://wiki.ubuntu.com/DebuggingKernelSuspend and provide us here with a resume-trace.

Thanks a lor for your help

[Frits82 (lakramer)]

Exactly same problem here with my Compaq C710ED on 8.10 kernel: 2.6.27-9-generic

[Kevin (linuxbugs-swiftninja)]

Andres, I did actually include a DMESG dump from the first successful suspend and subsequent (incomplete/failed) suspend. They are attached at the very beginning of the thread (first two posts), and seem to be what that DebuggingKernelSuspend article you link to are trying to get at..

Quoting the linked article:

"You have about 3 minutes to start this boot process before the information saved in the RTC gets corrupted.

Start a console and enter:

dmesg > dmesg.txt"

.. unless I'm missing something (which is entirely possible) that's what I've provided with the original bug submission.

That said, this issue (and lack of resolution thus far) has forced me back to Windows, so I'm unable to provide any additional information to this bug report. However it looks like there are lots of other people with similar problems -- as well as a few confirmations that this happens with 8.10 as well -- so should you require more information perhaps they could provide it?

cheers.

[Pieter Lenaerts (e-type)]

I have followed the DebuggingKernelSuspend article as well, but failed to notice anything resembling the wanted debugging info.

Both my dmesg outputs are in attachments.

[torquill (spammo-hung)]

I can confirm this on my Presario c700 running 2.6.27-11; I had the exact same problem with Hardy (bug #217400). I'll attach my dmesg, lspci, and lsmod outputs (there is no change in lsmod/lspci after the first suspend).

When I followed the DebuggingKernelSuspend instructions, the only thing remotely like the desired output was the following three lines:

[ 2.139221] Magic number: 9:6:177
[ 2.139312] tty ttyr3: hash matches
[ 2.139427] acpi device:0d: hash matches

This is not the same syntax as mentioned in the website, but it's similar enough to note. Nothing else stood out.

I have a portion of my syslog which shows the messages from the first suspend, first resume, second suspend, and subsequent reboot; I can attach it if desired, but the only thing I can see that's odd is that the second suspend cuts off in the middle of taking down ethernet.

[nola mike (abatzis)]

i also didn't get anything resembling a module on my dmesg trace. nonetheless, here it is. i had read elsewhere that the problem is due to ram timing or something else beyond my comprehension, rather than a hanging module.

[Andres Mujica (andres.mujica)]

Thanks for all the input, i'm marking this as confirmed

[LeoGnu (leogiurdanella-gmail)]

Exactly same problem here with my Compaq C769ED on 8.10 kernel: 2.6.27-11-generic

[LeoGnu (leogiurdanella-gmail)]

Bad News, I compile de new kernel 2.6.28.3 and nothing, the bugs appears again.

[LeoGnu (leogiurdanella-gmail)]

Today I install new kernel 2.6.29.1 and...... the same problem. I think that problem could be the Intel-xorg Module.

Hi Kevin,

Since you are the original bug reporter, I'd like to hear from you. Care to test and confirm this issue remains with the latest development release of Ubuntu (ie Karmic). ISO CD images are available from http://cdimage.ubuntu.com/releases/ . You should be able to test suspend using a LiveCD if you didn't want to install/upgrade just yet. Please let us know your results. Thanks.

Hi Kevin,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/karmic . However, note you can only test Suspend, not Hibernate, when using a LiveCD. If the issue remains, run the following command from a Terminal (Applications->Accessories->Terminal) it will automatically gather and attach updated debug information to this report.

apport-collect -p linux 234519

Also, please be sure to take a look at https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume . If you can provide any additional information outlined there it would be much appreciated.

Additionally, if you could try to reproduce this with the upstream mainline kernel that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Thanks in advance.

Hi I test with the last ISO of karmic (alpha4) and still the same problem.

[Ripliancum (jstras27)]

Same problem still exists with Karmic. I also tried the newest releases of OpenSuse and Fedora, both had the same problem. My computer suspends just fine under any version of windows. Wish they could figure this one out.

[enoeske (enoeske)]

I have this same issue with a compaq C700 series (C714nr) and all versions of ubuntu including Karmic. I can suspend once and it works fine. Second time, it won't wake up. I just updated the BIOS from F.06 to the latest F.34 thinking it would help but I still have the same issue. I'm a nooby though. I've been using ubuntu since 7.10 but don't know much about what happens in the background. If there is anything I can do to help solve it, let me know.

[bifurcation (bugs-launchpad-net-icetree)]

Exactly the same happens with my Compaq Presario C700

is anyone working on this? very frustrating bug...

[youbonetu (armand-rock)]

i just decided to switch my laptop to ubuntu and this bug affects me...

i started off a Ubuntu 9.04 install CD and then upgraded it to 9.10

I have a Presario A900 and i'm using kernel 2.6.31-16-generic

i tried changing to hybernate when i close my laptop but when i re-open my laptop the laptop feels warm so i think something still runs when i do hybernate....had to go back to default behavior instead....

anyways i have the same issue in that i can close my laptop and resume once...but the second time i get a black screen and my only option is to turn off the power by holding the button down

[Philip Guyton (phil-lxnet)]

@youbonetu there is a very similar (possibly duplicate) bug #352583 which concerns directly the A900 but does seems to be identical in other respects to this bug report, concerning the C700.

[Philip Guyton (phil-lxnet)]

Pieter Lenaerts has noted in Bug #352739 that it seems to be a duplicate of this one also. I couldn't mark as such as got ".. is not a valid bug number or nickname." when I tried. That bug is down as affecting 13 people at time of writing this.

[josh (sebasttj)]

I tried installing Karmic i386 on my wife's C700 the other day, and it suffers from this bug. It is 100% reproducible -- first suspend/resume works, second fails. If you search for bugs like "second resume", you'll find lots of different types of laptops all with the exact same problem. I did some googling and found this:

http://bugzilla.kernel.org/show_bug.cgi?id=11963

I also found the tboot project on Sourceforge, which is an Intel-created program that's supposed to address issues with Intel TXT on Linux. It requires the use of Xen, which I'd never set up before, and Ubuntu doesn't have an official Dom0-compatible kernel anyway. I couldn't get it to work before my wife insisted that I just reinstall Windows so she could use her laptop again.

Yes, fixed for me too by manually installing the 2.6.35 kernel for maverick in lucid.

Downloaded from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-maverick . The v2.6.35-rc1-lucid did not fix the problem for me.

Thanks LeoGnu ;-)

> Bug description:
> I have a Compaq Presario C756CA Laptop (which is in the C700 family), which has an Intel 3945 a/b/g wireless, Integrated Intel 3100 graphics chipset (using whatever free driver installs by default in Ubuntu), Samsung LCD display, "Syntek" Integrated Web-camera, Alps touch pad (running apparently with the synaptic driver), SATA 160 gb hdd, 2gb ram, Intel Core 2 Duo 1.6 ghz CPU. I have upgraded the firmware on the laptop to the latest, which I believe is F31 (released in March 2008).
>
> Running Ubuntu 8.04 (Hardy), fully updated as of May 24, 2008. ( Linux  2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux ).  This problem "fails" out of the box. I also get the same behavior on Fedora 9 RTM out of the box.
>
> Suspend to RAM works the first time. Resuming is fine, the first time.
>
> Suspending to RAM a subsequent time completely freezes the machine. Can't switch to terminal window. Have to hard reboot (press and hold power or pull battery)
>
> Hibernate works most of the time, although half of the time it comes back and says Hibernate failed (After I've already resumed from the hiberfile ;))
>
> Symptoms on second resume: No video. No image. No LCD Backlight; I believe webcam cycles on and off once and hard drive accesses once, Caps lock key is NOT flashing (kernel doesnt seem to be panicking). Does not respond to terminal switches (ALT+F1, F2, F3, etc), makes no difference if X is running or not.

> I have tried some of the HAL fixes on http://people.freedesktop.org/~hughsient/quirk/index.html . No success.
> I have tried competely disabling everything USB using RMMOD, disabling my Intel 3945 wireless using both RMMOD and editing the suspend modules list, no success.
>
> sudo pm-suspend adequately reproduces the problem, various --vesa options seem to make no difference, although I'm game to try a specific combo if someone has one that works for this config. I tried using the sleep.sh script in ubuntu, it produces the same behavior.
>
> I will attach my HAL list, a DMESG report on first suspend, and a DMESG report on the second suspend (which requires a hard reboot), although I'm not sure that the second DMESG dump is "good".

Correction
Kernel downloaded from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-maverick
Now all my laptop c708 works on linux Lucid

Declining the Maverick specific nomination for now and leaving this open against the actively developed Ubuntu kernel (which happens to be Maverick at this time). Will re-open the nomination should a fix be narrowed down which we can confirm specifically resolves this issue in Maverick.
