Bug Description

Just installed Tribe 5 (gutsy gibbon) Kubuntu on my laptop. I installed to hard disk and started the newly installed system.
When putting the laptop in suspend, the laptop does NOT go into suspend and completely hangs.

Hi Willem, thanks for your bug report.

Could you please precise the model of your laptop ?

Thanks.

Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.
4. Please follow this procedure : https://wiki.ubuntu.com/DebuggingKernelSuspend

For your reference, the full description of procedures for kernel-related bug reports is available at [WWW] http://wiki.ubuntu.com/KernelTeamBugPolicies. Thanks in advance!

Requested info is the following:
Laptop: Toshiba Satellite A110-228

Uname -a: Linux gutsy-test-laptop 2.6.22-10-generic #1 SMP Wed Aug 22 08:11:52 GMT 2007 i686 GNU/Linux

Another dmesg file, created ASAP after hang of suspend (this time, suspend went OK, but laptop hanged on resume)

Thank you. I'm marking this as triaged. I extracted the 'hash matches' :

Something has definately happened since fix of bug #129226, my suspend has broken since that. I don't get any errors anymore in syslog, so I guess this is a different bug from the Macbook patch originated one. This is on Asus M2NPV-VM and Athlon X2 4600+.

4. I found the lines

there where not 'hash matches' below that.

And the other log...

Question: I report several bugs for (k)ubuntu, like this one, but is anyone on earth working on these bugs? There is no feedback at all... Hope there will be a solution?

Error is still in 2.6.22-11 which I just downloaded.

Hi,
i have found the same problem in this kernel version. I send to you my dmseg log...may be can help you.

Same thing here (probably)
Asus a9rp (https://wiki.ubuntu.com/LaptopTestingTeam/AsusA9RP) and it used to wrk perfectly under feisty. Have not worked during the last upgrades in gutsy.

Symptoms: Suspend to ram gives a black screen with a blinking underline in the left upper corner of the screen and a blinking light indicating that caps lock is turned on-off-on-off rapidly.... (Which it is of course not.) Suspend to disk just blankens the screen and then starts over back into gnome.

I'll attack my outputs as well.

Same here with a Dell Inspiron 6400/e1505 with Ati Radeon X1300.
Would my information be helpful or is it enough with the reports already posted?

Superficially, this smells like a duplicate of the following:

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/121653
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/126214

The symptoms described are similar to what I and other have experienced, anyhow.

If the original reporter has an ATI graphics adapter and is using the fglrx driver, the problem is that fglrx is having problems with SLUB-enabled kernels (http://lwn.net/Articles/229984/). A workaround is to compile a custom kernel with SLAB enabled instead of SLUB.

I'm having similar problems with my 2.6.22-12 kernel, and I suspect it has to do with the SLAB/SLUB problem. I'm wanting to recompile my kernel. Can anyone show me how it's done. I tried doing it, and ended up with a bloated modules folder, and a non booting system. I'm having trouble at the "make menuconfig" part of the process - most of the configuration options are foreign to me (but I do see the SLAB/SLUB option). Is there any way to maybe get a .config file that is the same as the stock ubuntu one, and then just flick the switch on the SLAB/SLUB?

Help much appreciated.

Isaac Su (me-isaacsu) wrote :

I'd like to confirm that recompiling your kernel with SLAB instead of SLUB fixes this problem. Thanks to Terry for showing me how to do it.

Lynoure Braakman (lynoure) wrote :

Is it possible for the cause to be the same even if one doesn't use the fglrx driver? Because I honestly don't use it, and still have this problem. Should I start a new bug report instead?

I'd be grateful if someone else tried with ati card, but without fglrx, too.

My card is not supported by the X.org ATI driver.

I tried it on a Radeon 9800 notebook with the X.org ati driver. It
suspends, but when woken up again the screen stays blank.
Ctrl+Alt+BkSp does not help.

My Thinkpad T60 (X1400 video) suspends fine with the xserver-xorg-video-avivo driver, with fglrx it would "stick" while blinking the suspend LED. No fglrx, no problem.

On My Toshiba Satellite A110-228, NO fglrx, BIG problem...

Latest update (actually a fresh install bit still) to 2.6.22.14 and the opensource ati-driver seems to have fixed the sleep issue. The rt kernel still refuses to go to sleep though, but it stops later than the blinking cursor. Shoould I file a seperate bug report?

I'm running into this problem too. I have an IBM x22 and Suspend has always worked (Edgy, Feisty, Fedora Core 5,6). I even had a custom 2.6.22 kernel that could resume. currently I put is to sleep and then it hangs when coming out of sleep the little moon light that indicates sleep mode flashes like it's resuming and continues to do so indefinetly. I am not suing fglrx (there are none for my Mobility 6L MY)

I did a recent upgrade (102 packeges) and now my Laptop fails to make it into sleep. The light starts flashing, USB peripherals are disconnected and then nothing else happens, except that the light indicating going into sleep continues to flash.

Just confirm, My laptop IBM Thinkpad T60 with ATI Mobility Radeon X1300: Kernel 2.6.22-14-generic
1. With ATI restricted driver fglrx 8.37.6, Laptop cannot enter suspend mode. (crescent moon flashing, computer hang up, blank screen)
2. disable ATI restricted driver, xorg has vesa as generic driver, laptop CAN enter suspend mod and resume without problem.

1. I haven't been using the fglrx driver (it's not available for my hardware ATI Radeon m6 ly) but instead the open source ATI driver. Could not suspend using 2.6.22-14 kernel, feisty kernel or custom 2.6.23.1. (with SLAB instead of SLUB)

2. changed to vesa as posted above and now laptop is able to resume from suspend.

laptop sleep issues extend beyond just the Proprietary ATI driver.

I do NOT have an ATI card and do NOT use the fglrx driver and still my laptop never wakes up from resume. In feisty, everything works fine. So again, for me, this bug is not related to either ATI or fglrx...

I pointed that out mostly because the ATI fglrx problem made it into the release notes, but this problem doesn't appear to be getting the same attention (maybe do to some confusion).

Just a few things to mention. . . .

The symptom of this particular bug, failure to Suspend, is specific to the hardware used. So while many of you may have the same symptom they really should be different bugs since your hardware differs from the original bug reporter. It would be helpful if everyone were to test with the latest Hardy Alpha release, http://www.ubuntu.com/testing/ . You should be able to test using the LiveCD. However, note you can only test Suspend via the LiveCD, not Hibernate. If you still experience issues, and your hardware differs from the original bug reporters, please open a separate bug report for your hardware using "linux" as the package. The bug report should contain the information requested at http://wiki.ubuntu.com/KernelTeamBugPolicies . The following wiki may also help: https://wiki.ubuntu.com/DebuggingKernelSuspend. Additionally, it would be great if you made the titles of a new bug report contain information about your system. I apologize for any inconvenience this might cause but appreciate your cooperation.

After having said that, Willem can you comment if this is still an issue for you with the latest Hardy Alpha release? We'll keep this report open against the actively developed kernel but it will be closed against 2.6.22. Thanks.

Changed in linux-source-2.6.22:
status: Triaged → Won't Fix

status: New → Incomplete

Hello,

With Alpha 5 and all the latest Hardy updates this issue is currently
resolved on my laptop. Don't know if it will re-appear somewhen, but for
now I can confirm it's fine!

Does Launchpad not allow splitting bugs into different ones? At least some of the users do specify their hardware.

Thanks for the update Willem. I'm glad to hear things are working for you. Since you are the original bug reporter, I'm going to go ahead and mark this "Fix Released" against the Hardy kernel.

Lynoure Braakman, unfortunately launchpad does not yet have the capability for splitting comments into new bug reports. So for those of you who are still experiencing issues, please open a new bug report. Thanks.
