Sony Vaio TZ11M/N suspend and hibernate problems

[Peter Cooper]

This is using Gutsy.

Suspend always results in a failure to resume. Black screen, no hard drive activity, no response to caps lock key etc.

Hibernate seems to only work once after a reboot. All subsequent attempts to hibernate result in one of the following situations:

1. A screen lock dialog after a few seconds (ie no hibernate action, but no hard lock either!)

2. Appears to successfully hibernate, but subsequently a failure to resume with disk activity visible, but otherwise a black screen with blinking underscore cursor, no response to caps lock key etc.

3. A weird hard lock with either a black screen or blinking underscore cursor, no response to caps lock key, power light and disk light permanently on. Appears to stress the system, as the cooling fan spins up and doesn't spin down.

This behaviour is fairly consistent, but doesn't quite match any of the other bug reports I've seen.

Thanks!

Hi Peter,

Care to test the latest Hardy Heron Alpha release? The Hardy Heron Alpha series was recently released which contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to then test the new kernel via the LiveCD. Please note you can only test Suspend from the LiveCD, not Hibernate. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ . Thanks.

I burned a CD with today's Hardy Heron Alpha (i386) live-cd.

The shutdown dialog in Gnome did not present a hibernate button as Leanne suggested. I clicked the suspend button, but the laptop continued to operate with full-fan, power light on, no disc activity for ten minutes with no sign of suspend activity, and the system had to be hard rebooted (holding power button for 10 seconds) before any response to keyboard or touchpad occurred.

Looking at Ubuntu forums, I see http://ubuntuforums.org/showthread.php?p=4469268 where there was much earlier discussion about interrupts and audio modules (now talk about hippo) to resolve suspend problems. Unfortunately the suggestions didn't work for me.

Can I provide any additional dumps from the live-cd? The lspci stuff again?

Thanks!

Hi Peter,

Sorry for the delayed response. On Hardy, care to capture your dmesg output after a suspend/resume cycle as outlined here: https://wiki.ubuntu.com/DebuggingKernelSuspend . You may also want to give Hardy Beta a try. Thanks.

Small breakthrough, suspend worked for a few weeks with a recent Hardy kernel release after I changed the /etc/modprobe.d/alsa-base file's line referring to the Intel sound driver:

options snd-hda-intel

to

options snd-hda-intel model=hippo probe_mask=1

according to part of the thread in http://ubuntuforums.org/showthread.php?t=514292&page=15

And so long as I had the wireless switch to off (!).

But then it stopped working after I accepted a kernel update, from memory 2.6.24-16 going to -17. Gah. This time, suspend attempts sometimes dropped crud onto the display, before the hard lock, with one error referring to the iwl4965 module already having a zero count or something.

On an off-chance, next reboot I decided to try and pre-emptively unload the module before suspend, which I did manually. Ahah! It worked.

So I added the following line to /etc/default/acpi-support

MODULES="iwl4965"

And voila! I get reliable suspends now. I AM REALLY REALLY HAPPY ABOUT THIS :-)

Removing the line from the file results in failure during suspend of the "flashing underscore" with hard lock type, so I'm pretty sure something about this module is problematic.

Hibernates (or sleep-to-disk) still fails with endless console references to count=0 for a USB reference.

And while rolling back my changes, I realise I missed what might be the most important piece, adding a line to /etc/pm/config.d/modules

SUSPEND_MODULES="ehci_hcd uhci_hcd"

Hi Peter,

Just adding a note that I'm moving this bug forward to the linux kernel package. Beginning with the Hardy development cycle the kernel package naming convention changed from linux-source-2.6.xx to just linux.

Also just curious if you'd be willing to test the latest Intrepid Ibex 8.10 Alpha release and verify if this will be an issue. http://www.ubuntu.com/testing . You should be able to test Suspend from a LiveCD (you can't test Hibernate though). Thanks.

[Leann Ogasawara (leannogasawara)]

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.

--or--

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 http://www.ubuntu.com/testing 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.
