Bug Description

Using Ubuntu 10.04 32 bit Desktop, the system suddenly and unexpectedly powers off either when booting or when resuming from suspend or hibernate. If waking from suspend, this happens after the login box appears but even before I have begun typing my password. Unfortunately, this happens only once in about 7 or 8 suspends and not everytime. This is on a Dell Vostro V13 laptop.

After powering on the system again immediately after the problem has occurred, I have checked kernel.log and /var/log/messages and found nothing out of the ordinary there.

Re-installing 10.04 did not help. To confirm that this is not a problem with the hardware itself, I have now downgraded to Ubuntu 9.10 since a week and found that the problem went away.

Since I am now on 9.10, I did not use "ubuntu-bug" to report this as I am unsure how useful the information would be on this version of Ubuntu. However, if needed, I can do an apport-collect on 9.10 if it helps.

Hi Anoop,

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/ . 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 588194

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.

On Karmic, upgrading from kernel 2.6.31-21 to the recently available 2.6.31-22 causes the bug to appear in Karmic as well.

I also confirm that this happens in the latest Fedora 13 (Live CD), so it appears to be an upstream bug.

The problem seems related to the way ubuntu hibernation work.
The problem disappeared after installing "tux on ice" version of kernel suspend to disk implementation (using version at ppa:tuxonice/ppa):

It appears to be an acpi issue since passing acpi=off has made the problem go away (at least so far). I've also tried passing acpi=noirq , acpi=oldboot , noapic , nolapic , noirq (of course one at a time) - but none of those helped. Turning off the entire acpi stack seems extreme and I'd rather not do it. Besides, turning off acpi causes my touchpad to stop working.

Tried the latest mainline kernel 2.6.34-lucid with no luck.
The 'tux on ice' kernel also has the same problem.

Hi, I have to confirm this bug on a Dell Vostro V13. I'm running Arch Linux however (kernel / 2.6.35-ARCH). Just to inform that it's not a strictly ubuntu-bug :). I'll keep searching and looking to this thread.

I forgot to mention two things:
- it is on the same hardware than the original reporter (Dell Vostro V13)
- in my case it is much more frequent than once every 7 or 8 suspends, actually I've never been able to successfully suspend more than twice.

Anybody knows what it means?

gpothier (gpothier) wrote :

I did some more testing and although it seems several devices cause suspend/resume problems, the biggest issue is with bluetooth and usb.
I went to the bios settings and disabled all the integrated devices. In that configuration I did 10 suspend/resume cycles without problem.
Then I started enabling a few devices. With WLAN enabled I had one lock-up out of 10 suspend/resume cycles, but it was a lockup during suspend, not during resume, so it is probably another issue.
However enabling bluetooth makes it impossible to suspend/resume more than once or twice (after the second resume, the machine powers off during resume).
But the strangest thing is this: disabling bluetooth but enabling outside USB ports systematically triggers the unexpected power off during boot, the system becomes unbootable.

gpothier (gpothier) wrote :

Kenneth: your comment that the issue is fixed is for Arch Linux, right?
On Ubuntu I've tried mainline kernels, and the good news is that the currently available 2.6.36-rc6 kernel (http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-rc6-maverick/) almost fixes the issue: I still observe these unexpected poweroffs during resume, but much less often; and the bluetooth-applet disappears after resume, although bluetooth is working fine.
I also tried the mainline kernel, which does not fix the problem.

Kenneth (khenderick) wrote :

Yep, so I'm guessing it has something to do with the kernel or the intel videodrivers (as the problem did not occur when I put i915.modeset=0 in grubs kernelline). As you didn't get a fix with your it might be the intel videodriver that is causing our trouble. Maybe you can try the very latest intel driver available for Ubuntu?

Kenneth (khenderick) wrote :

It didn't fix it completely, it's just less frequent now :(.

gpothier (gpothier) wrote :

Same here, with the 2.6.36 mainline kernel, in real-world usage I still observe the unexpected poweroff quite often, around once in two or three suspend/resume cycles. It seems that if the machine remains suspended for a while it is much more likely to occur.

gpothier (gpothier) wrote :

I've been testing the 2.6.31-22-generic kernel (from Karmic) on my Maverick install, up to now I've *not* observed a single poweroff. I'll update this bug in a few days to confirm it really works with that kernel.
(the only issue is that the internal microphone doesn't seem to work with that kernel).

Anoop P B (anoop-pb) wrote :

I can confirm that the problem occurs on 2.6.31-22-generic kernel on my Karmic (as I have mentioned earlier in comment #18). I have at times experienced a dozen good resumes before the problem appears again. It does not occur at the same frequency. So even after several successive good resumes, I have experienced the bug in quick succession afterwards.

Currently, the only good config that works for me is 2.6.31-14-generic on Karmic. Installing linux-backports-modules-alsa-2.6.31-14-generic makes the internal microphone work on that kernel.

gpothier (gpothier) wrote :

Thanks for the tip, indeed the alsa backport fixes the mic. I'll keep testing the kernels.

gpothier (gpothier) wrote :

Also note that this machine is Ubuntu Certified:

The page says that it is certified for 10.04 LTS, but the 2.6.31 Karmic kernel is the last known to work. I think the certificacion should be removed while this bug is not fixed.

gpothier (gpothier) wrote :

I just tested with the recently uploaded maverick kernel: I've not experienced the poweroff issue, but that's because the machine fails to suspend... Either it hangs in a semi-suspended state (but the LCD backlight is still on) and has to be hard-reset, or it just attempts to suspend and immediately wakes up.

I also have the same problem.

actual kernel + (tried both)

It took me some month to realize the problem, because for me the "power off" at boot came very sporadically. Until today the 2nd try was always successful, but a few moments ago I had to boot 10 times to see the login-screen only at the last attempt.

From my observations the problem seems to get worse with any kernel update.

Hilmar Demuth (hilmar-demuth) wrote :

sorry, forgot to add:

I have of course also a Dell Vostro V13.

In order to solve the problem I upgraded the bios version from A01 to A05, no effect.

Andrea Cimitan (cimi) wrote :

in natty, with latest kernels (i guess the last two maybe), the computer NEVER resumes from suspend, and I can't get the login screen much more times.
This is a huge problem, the Ubuntu Certification should be removed until this is fixed, or people (like me) continue to buy laptops and they become unsatisfied from Ubuntu once they understand that they bought incompatible hardware.

Same bug with my Dell Vostro V13 and Ubuntu 10.10 64 bits.

I'm very disappointed because of the certification wich is visible on your website. I hope that you are resolving this important bug.

Burin_Khazad (burin-khazad) wrote :

With a more recent Linux Kernel (2.6.37), the bug doesn't appear as frequently as with the standard kernel. Since I install this new RC Kernel, I don't have the bug when I start my computer, only one time when resuming from suspend.

I install this Kernel from this website : http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37-rc2-maverick/

I have the same problem. My kernel version is on Ubuntu 10.10. I recently upgraded from 2.6.35-22-generic. I have not really found a pattern when it suspend forces a power down and when not.

I experience the same bug on my Dell Vostro V13 laptop. I installed Ubuntu 10.10 on an external USB hard drive.
On boot, I have to try on average three times to have a succesful boot. The two other times, the computer shut downs unexpectedly before displaying the Ubuntu splashscreen.
I tried several kernel version, to no avail (currently running 2.6.37 rc2).

This bug was solved for me when applying a patch proposed for a different bug : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/380126 (problem with the synaptic touchpad on the same computer model.
Apparenlty it is due to bad interrupts by the touchpad.
Hope this helps.

Burin_Khazad (burin-khazad) wrote :

Thanks a lot for the link Nicolas.

If someone is interrested, you can find the kernel 2.6.35-25.43 compiled with this patch in my website : https://www.isorez.fr/ftp

Kernel packages are for amd64 (compiled in my vostro v13 with Intel T7300). There is also a synaptics package in order to enable the multi touch of the touchpad.

Hope this helps. ;)

After the upgrade to Kernel 2.6.32-27 the bug didn't occure for some time, but today the powerdown happened once more.

Sorry, the bug also effect:

Ubuntu Kernel 2.6.32-27-generic

Hope the bug is fixed soon...
If I can help by testing a new patch for Kernel 2.6.32, please contact me.

I have a V13 notebook and the same problem happen using Debian 6.0 (kernel 2.6.32 AMD64) in power on and back to suspend and hibernate.

Since I added "acpi=off" in kernel line (on grub conf), this problems (power off during boot and ACPI error message) was solved. But I can't suspend/hibernate anymore... =/

I'm downloadind natty-alpha1 to test.
