suspend/resume broken on dell Latitude E6400 kernel 2.6.27-3

dmesg.log is obtained after following the steps from https://wiki.ubuntu.com/DebuggingKernelSuspend

I just got my Dell E6400, and did try suspend and resume once, and it worked for me, but I only tried it once. I am using Intripid Ibex and my kernel is given by:

$ uname -r
2.6.27-3-generic

Hope this helps!

I forgot to say that it worked once as well for me. And in fact two more times, each after an upgrade.

Previously, the standby/hibernate and resume functions tended to be affected by the kvm module(s). This was documented in bugs #113038 and #163862.

Is there a chance the observed behavior may depend on whether the kvm/kvm-intel modules are loaded? I seem to remember that suspend would no longer work after I had installed VirtualBox in an earlier version.

I apologize if this information is very vague. I hope that these hints would be helpful to the ones who want to play around with some settings to hunt the bug.

Thanks, some hints are greatly appreciated. Alas, on my computer there is no kvm module (lsmod | grep kvm does not return anything). If anybody have some other ideas, I would like to try them.

Removing the Dell project. This isn't a machine shipping with Ubuntu.

Does that mean that this machine will never be sold with Ubuntu?

It doesn't mean it will *never* be sold with Ubuntu, but it's not in the
current lineup of machines that has been, currently is, or will be
targeted with Ubuntu.

This seems to be fixed with 2.6.27-5-generic on my E6400 Latitude. I tried several times to suspend and it came back every time! Thanks to whoever fixed it! Hibernation even worked, though I only tested it once.

Still not fixed on my machine. Have you done anything special Rob? Maybe a specificity of my laptop is that I upgraded the Bios to version A03. Should I send the logs I get on 2.6.27-5 ?

I don't have anything special that I can think of. I installed Intrepid with A5, copied my home directories from my old notebook, and have been keeping things up to date. (I have proposed updates and every other kind of update selected in Sysaptic.) I am also using Bios A01.

Also broken on my E6400. Neither suspend to RAM nor suspend to disk are working with Ubuntu 8.10 beta. The machine is suspending and shutting down, but crashes on resume (magic-sysreq keys don't work) in either case.
Attaching output of lspci -nv.

Strange! I just tried suspend to ram with /etc/acpi/sleep.sh force in order to obtain further debug information. The first suspend did not resume correctly, the second one apparently did (I am writing from the resumed system). Sound however does not work again, I'm just getting distorted crackling noise.
Attaching dmesg.

Disregard the sound problem, apparently sound broke completely after some update. Deleting personal configuration files resolved that.

Suspend broke again after rebooting. I can't think of anything I did differently this time, once it worked I could suspend/resume multiple times in a row.

The same here. I could suspend/resume several times without problems on my E6400. Now, suddenly it seems to freeze my system regularly at resume.

I have copied an Intrepid beta to an USB stick using usb-creator. When I boot from that stick suspend works fine, just as it did with my hdd install some days ago. Booting from the harddisk with an up-to-date Ubuntu does not work though.

Also I tried to install a release candidate without adding any packages to default -> suspend does not work.

When I switch to a text-console and suspend by using "pmi action suspend" it _never_ fails to resume. Switching to the graphical console (ALT+F7) then freezes the system. This is 100% the case when I was logged in to Gnome. When X was in GDM no crash happens.

I tried the newest Kernel (2.6.28-RC2 I think) -> still freezes.

Here a list of packages and their versions of my live usb-stick with fully and reliably working suspend.

After at least 20 successful suspend/resumes using my live usb-stick (above), resume got frozen for the first time :-/

I tested suspend(ram/disk) on three Latitude E6500.
Suspend2Disk works (flackering display while suspending :(), but it stucks when resuming (empty grey unlock window, mousepointer stucks)
Suspend2RAM works often, last days it works less.

that is exactly what it looks like on my E6400 after waking up from suspend.

I tested this on three E6500 and one E6400 everywhere the same problem.

I think it's an Xserver problem:

Similar experience on my Dell E1505 (aka 6400) with ATI video card. Suspend works sometimes, but hibernate will not resume. This happened after I upgraded from hardy. So, I tried doing a fresh install, but have the same experience. I tried both 32-bit and 64-bit versions of intrepid, with the same result.

I edited the grub boot line to elimate "quiet splash" and noticed that the resume successfully unpacked the resume image file, but hung at the next step with the error message:

suspending consoles (use no_console_suspend to debug)

I tried this at the end of the boot line and it showed a little more messages, but still did not show any errors. It just hangs,

This is what's happening to me, I'm on a clevo m735T. I really hope this will be sorted out soon. It used to work for me on hardy. (I did update-manager -d from 64bit hardy)

Same here.

Microboard Centturion Plus, Turion 64 X2, Ubuntu 8.10 amd64 upgraded from Hardy. Video is ATI, by the way - not sure it's related, but I think it's worth mentioning, as someone here believes it may be an X problem. Suspend/hibernate works fine, but the system freezes on resume - grey screen, mouse pointer and locked touch and keyboard (on suspend) or only mouse pointer and black screen, no touch, no keys (on hibernate).

Ideas?

Kubuntu 8.10, Dell Latitude E6400 with intel graphics.

Resume mostly does not work with default settings. Problems appears to be with the xserver. I observed after a successful resume that xrandr reports a spurious "VGA connected" in addition to "LVDS connected".

Resume is working for me if I explicitly disable all outpus except LVDS in xorg.conf (I have not tested whether it would be enough to just disable VGA).

@Thomas Neff: I tried your workaround, but resume failed at the second try. For me only the "disable CPUs" fix works.
http://www.entner.net/blog/workaround-intel-graphics-and-suspend-in-linux-english

Robert's "disable CPUs" work around works for me, and I like it much better than disabling the VGA as I use this machine for presentations everyday.

Thanks Robert!

The only problem is that CPU frequency scaling cannot be properly changed using the gnome applet afterwards.
