Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at [WWW] https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in linux-source-2.6.22.

Following up my problem, I tried to execute f2disk. This command works the first time. However, from the second time on, my laptop resumes by showing a white cursor on a black screen.

Alexander, thank you for taking the time to report this bug and helping to make Ubuntu better. Can you please attach the following information:

* uname -a > uname-a.log
* cat /proc/version_signature > version.log
* dmesg > dmesg.log
* sudo lspci -vvnn > lspci-vvnn.log

Please be sure to attach each file as a separate attachment. Please note that the most useful information you can provide will be regarding the kernel crash. This is usually found in the dmesg output. However, if this crash completely locks up your machine, reboot to a known working kernel and try looking at /var/log/kern.log.0 to see if anything was logged there regarding the crash. Please attach kern.log.0 if anything useful appears. For more information regarding the kernel team bug policy, please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help and feedback.

Hi!

Here you go.

[Alexander (ak71vie)]

and here is the log-file /var/log/kern.log

it looks like there is something fishy with the sonypi - module.

[Leann Ogasawara (leannogasawara)]

Hi Alexander,

It looks like you have both the sonypi and sony-laptop modules installed. Can you attach the output of 'lsmod' so that I can verify? It is my understanding that sonypi is obsoleted in favor of using sony-laptop. You can even see by some of the dmesg output:

sonypi: please try the sony-laptop module instead and report failures, see also http://www.linux.it/~malattia/wiki/index.php/Sony_drivers

Care to try the following:

1. sudo rmmod sonypi
2. then try to suspend and resume

Please let us know of your results. If the issue still persists, the following might help, https://wiki.ubuntu.com/DebuggingKernelSuspend . Otherwise, you'll probably want to blacklist sonypi. Thanks!

[Alexander (ak71vie)]

Hi Lean!

lsmod | grep sony

yields

sony_laptop 32088 0
sonypi 23960 0

you are right, both modules are installed. Attached you find the output of lsmod (lsmod.log)

[Alexander (ak71vie)]

I have removed the module sonypi

(Uncomment the line "modprobe sonypi" in /etc/init.d/hotkey-setup! notice that blacklisting the module in /etc/modprobe.d/blacklist does not remove it permanently for some reasons)

now suspend/hibernate works!

thank you very much!

[Leann Ogasawara (leannogasawara)]

Hi Alexander,

That's great to hear this is working now. I'll be closing this bug report due to your last comment regarding this being fixed after blacklisting the sonypi module. For future reference you can manage the status of your own bugs by clicking on the current status in the yellow line and then choosing a new status in the revealed drop down box. You can learn more about bug statuses at [WWW] https://wiki.ubuntu.com/Bugs/Status . Thank you again for taking the time to report this bug and helping to make Ubuntu better. Feel free to submit any future bugs that you may find, we really do appreciate it.

[Alexander (ak71vie)]

Hi Leann,

notice that in few cases the green LED for AC-power on the front remains on after the hibernation process. I have to manually press the shut-down button.

best, Alexander.

[Leann Ogasawara (leannogasawara)]

Hi Alexander,

If you wouldn't mind, could you open up a new bug report regarding this new issue? It's more helpful to us and our development teams if bug reports target only one particular issue. Feel free to subscribe me to your new bug report. Again, as you did in this report, in your new bug report can you attach

* uname -a > uname-a.log
* cat /proc/version_signature > version.log
* dmesg > dmesg.log
* sudo lspci -vvnn > lspci-vvnn.log

And the dmesg output might be more helpful if you capture it after hibernation. Thanks!
