Thanks for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description doesn't yet have enough information.
Please include the following additional information, if you have not already done so (please 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' and attach the resulting file 'dmesg.log' to this bug report.
3. Please run the command 'lspci -vvnn > lspci-vvnn.log' and attach the resulting file 'lspci-vvnn.log' to this bug report.
For your reference, the full description of procedures for kernel-related bug reports is available at . Thanks in advance!

I'm seeing this too, with 2.6.20-12-lowlatency on a Thinkpad T30. (opensource ATI drivers for Radeon 7500, P4 @2Ghz, orinoco_pci wireless, e100 ethernet).

Hibernation used to work fine in edgy and in previous feisty kernels, though there had been a regression with hibernation+sound (vis. bug 80893).

T60 Thinkpad is also affected. And this bug is terrifying: I have restarted my thinkpad about 100 times in the last 3 weeks, because it hangs when going to sleep. Combined with fdisk changing the UUID label for the swap partition every couple of reboots (and thus failing to mount a swap without telling me), the usage of this machine is nearly unbearable.

I'm attaching file with:
uname -a

Same problem here on a Thinkpad T40. Hibernate has not worked since I began using Feisty Herd 4 (around 2.6.20-8 kernel). Hibernate has worked fine under Edgy though. Suspend to ram works Fine under Feisty. I have attached uname -a, lspci -vvnn, and dmesg after hibernate attempt.

some time it is because the feisty identify the disk as a sata
first you can
$swapon -a
if no show your swap is on.can't hibernate is caused by some other reason.
it's because swap not mount right
you can edit /etc/fstab and /etc/initramfs-tools/conf.d/resume
give the correct partition to swap and resume
/dev/sda1 .... swap

Update: Thinkpad T60p sleeps and resumes flawlessly with latest Feisty.

Linux pad 2.6.20-14-generic #2 SMP Mon Apr 2 20:37:49 UTC 2007 i686 GNU/Linux

The trick is to:
1) disable the graphics card warm up (for ATI cards).
2) disable/reenable powernowd in the sleep/resume acpi sequence:

My thinkpad R31 have the same problem in Feisty(Eddy is still ok),too.Mine originally is updated from Eddy and it happen.But on the day before yesterday,for some my fail hacking,I need to reinstall it.After doing a clean installing,I found that hibernating to disk work again(with some console messages not showing the usplash)!Maybe something wrong in updating?

Just with a little new problem :after hibernating to disk powered off,I powered it on .It come back to gnome fine with the hibernate LED light no stopping twinkling.

And also another one.Hibernating to RAM sometime work fine,but sometimes not.

...but I'm not sure about Step 1. What is the graphics card warm up (and how does one disable it)? I think I am up against Bugs 109403 and/or 109762 (hibernate works, but resume fails (after suspend) with SCSI I/O "dead device" errors...). I'm flailing pretty hard, here, so I thought I'd give this a whirl.


Chris (poser) wrote :

Never mind,

Presumably, this is referring to the POST_VIDEO option from /etc/default/acpi-support. Still no dice.


Chris (poser) wrote :


How sure are we that bug 109403 is really a duplicate of this one? I hadn't actually read the description of _this_ bug until now...but it seems to be more about hibernation than suspend. *shrug* (Incidentally, I recently fixed my own hibernation problems with information from bug 88377.)

Good luck all,

Felix Hagemann (flixh) wrote :

The same problem with hibernating disappeared on my Samsung X20 with
Feisty (upgraded from Edgy last week), when I stopped mounting my swap
partition by label
in /etc/fstab and instead gave the correct device name.

Interesting enough the swap partition was in use without any problems before
that change (as well as after) but hibernating now works.


Chris (poser) wrote :

I tried removing my /sys/power/image_size hack and editing /etc/fstab to mount swap the "normal" way, and things still hung when resuming from hibernation. *shrug* For me, manually setting image_size to something less-than-or-equal-to swap size definitely seems to be the fix. (Note: my default /etc/fstab--from a clean Feisty install--does not use the LABEL convention; it uses the UUID=<blah blah blah> convention.)

Aurelbu (aurelbu) wrote :

I still have the problem with my t42 with latest release...

Nevertheless, I found a workaround :
Install uswsusp
edit /etc/uswsusp.conf to add/change :

early writeout = y
shutdown method = shutdown

and the enjoy s2disk...

If one of these 2 lines is not set, the s2disk does not work (same behaviour than with /etc/acpi/
I hope it will help...

I can confirm this -- 7.04 (Feisty, fresh *install* from the *alternate* CD) on a Thinkpad R40:

$ uname -a
Linux whisker 2.6.20-16-generic #2 SMP Thu Jun 7 20:19:32 UTC 2007 i686 GNU/Linux

As the original poster writes: From choosing "System>Quit>Hibernate"

1. Screen Blanks
2. Sleep light starts blinking
3. X11 returns
4. Screen-saver password prompt

I found out that my swap wasn't used:

$ swapon -s
Filename Type Size Used Priority

That was all -- but I have a swap partition!

Then I found out that I had exactly the same problem as in bug 90526: the UUID of the swap partition as given by "ls -l /dev/disk/by-uuid/" didn't match the UUID of the swap partition in /etc/fstab. I replaced the UUID in /etc/fstab with the one found with "ls -l /dev/disk/by-uuid/", and after that, suspend to disk (a.k.a. hibernate) works. Now I'm waiting for the next routine run of fsck to see if it breaks again.

Following up on my comment above: the routine fsck run did occur, but it didn't break anything. Suspend to disk is still working.

This bug and related are very much on: Thinkpads with ATI graphics card don't hibernate with gutsy.

We are enduring the pain.

This looks like Bug 121653, which is for no suspend/hibernate with fglrx.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

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.


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 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.
