Bug Description

Using recent maverick kernels, my suspend has stopped working. It previously worked in lucid, and for much of maverick development cycle.

Now, closing the laptop results in flashing 'moon' and a switch of console out of X, with an unrelated message on the screen (I think it is gdk message, but don't recall exactly).

opening laptop back up, it is generally unresponsive. (alt-f1 -> alt-f7 do nothing).
I've had to hard power off.

I am also affected. The dangerous part of this bug is that the laptop suspends only partially. The thermal control (fans) are shut down, while processor and screen remains running. I am afraid that this combination can lead to fatal consequences to the CPU.

I have been experiencing this bug since one of the earliest builds of 10.10. I'm disappointed it has not gotten resolved in the final 10.10 release.

The system has a 50/50 chance of being put into the crash state. What I'm doing (browsing running flash, no browsers open, etc.) does not appear to have any impact on whether the system crashes.

Running Lenovo R60.

After upgrade, I closed the lid and woke up that my laptop battery was fully drained and the temperature in my backpack grew like in summer. My T400 is cold usually, so this bug is serious!

If you need help with testing, I'm in.

Could anyone who tested Maverick during its devolopment spot the version at which things started going wrong? Maybe that helps to track down the reason of the bug...

I am affected by this too. However I switched to my discrete ATI card and it seems to work properly. Haven't done extensive testing yet, but I haven't had a problem since I switched 3 days ago.

Apparently same thing on T400s; always seems to occur upon every suspend attempt (what with the data loss and all, I'm not inclined to keep trying, unless someone has a less destructive test methodology). Prior to Maverick (Karmic, Gutsy), suspend worked flawlessly. I'm seeing anecdotal reports of behavior that sounds related as early as April or March...is this really such an unpopular laptop series?

Anyone, beside problems with suspend, experience drop in performance on
3d acceleration(for example lp:#663328) and wifi. I mean it makes me
feel that after Lucid, Meerkat made my t400 a bit less smart.

Also, I don't have the model with 2 video cards, just with an Intel GM45
series, so this bugs is surely not caused by such details like used gpu.

@David et al.
This is definitely not an unpopular laptop series. I'm working for IBM and all of us employees worldwide are using Thinkpads, especially the T-Series, and so do others in IT and Business. About 10% of us IBM employees are using Linux on their workstations (=Thinkpads). I've been using Ubuntu for years now and suspend has worked flawlessly, as you say, even with Lucid.
About the pattern/symptoms: It seems to be entirely random. Sometimes it hangs several times in a row and then suspend works again... strange!

Another "me too", T400, I use suspend a lot and since upgrading to Maverick it hangs in about 10-20% of cases.

The last message printed on console is something like "Checking battery state", but I'm not sure if it's at all related to hangups.

Same here, I have a T400 and suspending it fails in about 50% of cases. Only way out is to switch the machine off.

Thank you for pointing out a solution. Suspend works like a charm for me now, too.

Suspend works, yay!
Thanks.

Same for me with T400s; above-mentioned mainline kernel deb restores suspend ability.

I tried the 2.6.36 mainline kernel and suspend indeed works like a charm again (it even wakes up faster than with the standard Ubuntu kernel, but I already noticed this with lucid, too). Also, I checked the 2.6.35 mainline kernel: it had the same problems as the Ubuntu version, so it is definitely a problem with the kernel itself and not with Ubuntu's patches.

Fortunately, with the 2.6.36 mainline kernel suspend works again. You can download the 64bit version at http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-maverick/linux-image-2.6.36-020636-generic_2.6.36-020636.201010210905_amd64.deb

Seeing the same behaviour on my T400s running 10.10. Suspend works half of the time. The other half the box freezes. Used to work fine with 10.04.

Scott Moser (smoser) wrote :

Well, I just installed linux-image-2.6.36-020636-generic in maybe 5 attempts to suspsend/resume, 2 of them failed. One was pretty much a stock "boot, open firefox, suspend", and it did not come out of suspend. The other left the moon flashing on the way into suspend.

Hi,

w/ 2.6.36 I also had major suspend/hibernate problems. Lately, that was an issue on LKML too http://kerneltrap.org/mailarchive/linux-kernel/2010/10/27/4638146 . Further, I had apparmor seg faults w/ the stock 2.6.36 LK.

As written in bug 666172 (marked as duplicated of this one here)
echo (disk|mem) >| /sys/power/state
always worked fine for me. However, from time to time I get Kernel Ooopsies using the Ubuntu Kernel. I attach 2 dmesg traces here showing that. I did "short-cut" the /usr/lib/pm-utils/bin/pm-action script to skip everything (hooks) but the suspend/hibernate action.

Currently, I'm trying the 2.6.35 stock kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-maverick/ It's too early to say if it also ooopses since that happens only once in a while. suspend/hibernate seems to be stable though.

/var/log/pm-suspend.log has never shown any issues. Just ended w/ the hooks section.

The vanilla kernel does not fix the issue on the X60 tablet. Still a blinking moon on hibernate and a running fan on suspend.

Your dmesg looks fine. It doesn't show a bug.

I tried backing off pm-utils to 1.3.0-1ubuntu2 (lucid), thinking maybe some changes there in the quirks that were determined were the issue.

thanks to 'wanted' in comment 18 above, I am now suspend and resuming 5 times in a row using up to date maverick.
What i'm doing is just running:

so, that works. However, I've not successfully set any quirks (/usr/share/doc/pm-utils/README.debugging) that got me consistent suspend and resume.

you can put the work around into the pm-utils path by adding the following to /etc/pm/sleep.d/10-lp-bug-625364. Note, its a work around, not a fix, but it makes me very happy to not crash. Note, you need to write the file as root, then make sure its executable (chmod 755)

there is nothing in dmesg, or at least no way to get at it that i'm aware of The system locks up, it basically suspends, but the moon remains flashing, and does not come out of suspend.
/var/log/messages has nothing.

I cannot find anything in dmesg either. With vanilla kernel 2.6.36 I have now twice successfully suspended to disk - but suspend to ram still fails (steady moon, but fan still blowing, system cannot be reactivated).

Additionally, the hotkeys FN-F4 / FN-F12 for suspend / hibernate do not work, but this may be another issue.

smoser,
       Is this still an issue for you in Natty? Also, does the pm-utils workaround work for you?

Folks,
     This bug has become unmanageable and has grown way past its initial report. As such, if you feel you are affected by this or a very similar issue, please file new unique bugs for your hardware. You may reference this bug in your report so that the discussion here is not lost.

Thanks!

The work around I posted, with the chvt in comment 43 worked for me in maverick.

    drm/radeon/kms: reorder display resume to avoid problems

    On resume, we were attemping to unblank the displays before the

    waiting for things that are not yet programmed. Re-program
    the mode first, then reset the dpms state.

    This fixes the infamous atombios timeouts on resume.

Ubuntu 11.04 "Natty Narwhal" is using the 2.6.38 kernel.

This patch was also included upstream in kernels 2.6.36.3 and 2.6.35.11. Confusingly, it's mentioned again in the upstream changelog for 2.6.35.12, so I'm not sure whether that means it wasn't applied properly in 2.6.35.11. Either way, the 2.6.35-27.47 maverick kernel is based on 2.6.35.11 and the 2.6.35-29.51 kernel in maverick-proposed is based on 2.6.35.12.

Odd: on my T400, still running 10.10, it seems the latest upgrade to
kernel 2.6.35-27
fixed the matter -- at the very least, the bug is not reproducible
anymore, whereas before
I saw it without exception.

with natty live cd suspend/resume works on tp t400. after instaling frzes on resume

tully's comment #151 hints at the same thing I hinted at in #103 - did anyone ever look into this? i.e. the problem being swap or other fs related?

difference is that i can not switch to X with Alt+F7. system is completly frozen.

/ - ext4
/home - ext4 not encrypted

i found this as last message in kern.log:

I disabled security chip in BIOS setup on my T500 and after that it works just fine both in Maverick and Natty.

These issues reek of serious ACPI trouble with the recent kernels. I'm also on the Ubuntu on MacBook discussion list, and here brightness keys stopped working with Natty:

http://ubuntuforums.org/showthread.php?t=1603365&page=31#308

Same thing on my laptop - I'm also missing /var/log/messages now (don't even know how that's possible and if that's related). My desktop (i7 920 on ASUS RoG II GENE) kernel panics if booted without noacpi nolapic.

I'm starting to believe that the ACPI code in the 2.6.38 kernels may be seriously flawed, and that the kernel team has some massive work to do before any of us see all of our issues resolved - and I fear that the Ubuntu team can's do a whole lot...

I haven't found one. :(

As reported by Scott Moser on comment #142, I hereby confirm that the suspend issue (endless flashing moon requiring a hard power off) no longer appears on my T400 (with Intel graphics) since I have upgraded to Kubuntu Natty 11.04, and this without any workaround. My laptop now goes correctly to standby mode (I tested a few tens times over two weeks now without any one failure).

I have exactly the same behavior as described in #156. Since I switched back to the normal Kernel 2.6.38 (without PAE) suspend works fine again.

I'm experiencing the same bug on a ThinkPad T420 with up-to-date Ubuntu Natty. Please reopen.

The bug is very serious. Just like others, I learned about it the hard way: closed the lid, put my laptop inside the bag, took it out about half an our later, and was shocked to see the laptop heated like on fire, and the fan running full power. Also, the CapsLock light was blinking.

This issue should be mentioned in the ReleaseNotes, as it possibly can damage hardware!

strav (strav) wrote :

May I know why this bug has been set to "fix released" on Natty? It seems that so far, all we have is post #35's duct tape fix (which, in my case, helped but didn't completely fixed the issue) and unless I'm missing something, I haven't encountered an official update fixing the issue.

Strav (comment #166): I'm just as confused as you... Ever since installing Natty a few weeks ago on my T500 I've NEVER been able to suspend. In my case the moon AND the Caps Lock indicator keep blinking until I forcefully power off. Even the #35 fix (and other fixes of similar kind) have done nothing to help. This bug is unfortunately serious and still very much alive!

Bernt Ribbum (bernt-ribbum) wrote :

As asked in comment #162:

Yes, for me this issue was related to using the PAE kernel! I have done lots of experimenting with this, and my T500 is now happily suspending and resuming. Can't be 100% sure of course, but by the looks of it, *everything* works!

To get a working system, I have applied the following fixes:

* "duct-tape" fix to switch to TTY1 on suspend (#35)
* disabled security chip in BIOS (#154)
* switched to generic (non-PAE) kernel (#156)

I'll come back if I am wrong, but for now I'm happy!

Bernt Ribbum (bernt-ribbum) wrote :

Well, happiness lasted about an hour...
All the way until I started a virtual machine in VirtualBox, that is. That made me reinstall the driver vboxdrv, which started the symptoms all over again..! It wouldn't suspend.

This time I won't blame Ubuntu of course, but rather the BIOS (or at least the hardware). Something is fishy with this machine when it comes to addressing >4GB. Have anyone ever tried to install a 64-bit OS on it?

I have been using 64-bit Ubuntu (8.10, 10.04 LTS) in Thinkpad T400
with Intel graphics. They are fine in general. There are issues here
and there--some could be annoying. The latest is the problem with
suspend-resume and/or graphics. My issues are described here:

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/777956

I tried backported 2.6.35 and 2.6.38 series kernel available for
Lucid---I keep having issues with respect to suspend/resume. 2.6.35
problem is as described in this bug page (moon light blinking and
suspend was hung); 2.6.38's problem is with waking up from suspend
(something X-related; I can't describe in full right now). Both are
occasionally happening (and don't know when they will happen). It
feels like I want to give up using Ubuntu on this laptop.

Thanks Wirawan,

I also suspend the machine all the time, so it is critical for me that
it works. In my case, however, Ubuntu will NEVER let me suspend. I feel
like giving Ubuntu up as well. Do you have a viable alternative? I would
like to stick to the .deb system if possible, and the installation
medium must be CD (can't write DVDs on this machine...)

Hi Bernt: I recently installed Debian 6.0.2 (Squeeze) on my laptop. I think this distro runs smoothly on this laptop. Exception is the firmware for intel iwlwifi, which must be installed separately (not a big deal). I am using kernel 2.6.38 from squeeze-backports to get rid of "flickering" problem existing in 2.6.32 kernel line. I probably should write a fuller report in ubuntu forums instead of here. I just want to give you some lead if perhaps this would help you too. I love Ubuntu and the efforts made by Canonical to popularize linux. However I am also disappointed that critical issues like this always exist from release to release. Debian seems to pay better attention to stability and reliability for "business"-like uses.

Debian was not a great success, unfortunately. I was asked for some proprietary driver when installing (which I don't have!), and now the machine won't connect to my wireless network... So back to square one. If I reinstall Ubuntu and stop running virtual machines it should work!

Same that I experienced, but in my case I had no idea how to deal with it. It asked for a driver - how to get hold of that?

Hi all,

I have a T400 running 64 bit Ubuntu 10.10 with 4GB ram.

My suspend fails intermittantly and my mouse lags, at every startup and wake up. It looks like the cpu's are up to
30% when the mouse lag occurs. I was using kernel 2.35.x I'll need to look it up.

I switched to kernel 2.6.32-28-generic, what I used with 9.10 and haven't noticed either problem yet. I found the
kernel version by searching Ubuntuforums.org, I shouldn't written down the URL....

I'll post back if I have another suspend fail.
