Thinkpad T43p: shutdown after resume

[hunger]

Binary package hint: acpi-support

Hi!

My thinkpad T43p (description of HW see wiki) now suspends/resumes properly with the new 2.6.15-22 kernel... but it starts a shutdown immediently after the resume is complete.

[hunger (hunger)]

Some more info:
I use "pmi action suspend" to suspend.
Resume is initiated by pushing the power button.

The shutdown happens right after the GUI is up again. I suspect that kpowersave/klaptopdaemon trigger on the power button press used to resume the laptop.

This happens with both kpowersaved and klaptopdaemon installed, so it does effect all kubuntu users.

Hi,

there's a patch in 2.6.17-rc3-mm1 which suppresses tthe power button event on resume.

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc3/2.6.17-rc3-mm1/broken-out/acpi-suppress-power-button-event-on-s3-resume.patch

But can't you resume be pressing the Fn button?

Best regards,
Whoopie

Unfortunately the Fn-Button workaround does not work for me. It does cause the laptop to blink its LEDs, but nothing more:-(

No, this bug is not a duplicate of #34389!

Hardware info for this laptop is here: https://wiki.ubuntu.com/LaptopTestingTeam/ThinkpadT43p-2668

Hunger, can you also include the ouput of:

  cat /var/lib/acpi-support/*-*

so that we can white-list your laptop as having working Suspend.

This is the requested output:

Any idea how to stop the shutdown happening right after the resume? That does spoil the fact of having a working suspend somewhat;-)

How are my chances to see this issue fixed in time for dapper?

I'd hate having to reinstall breezy... dapper is such a huge step forward. But then I need to be able to suspend my laptop or it will chew through its batteries:-(

[hunger (hunger)]

acpi-support 0.83 does not fix this issue, even though the changelog claims it might:-(

[hunger (hunger)]

I just upgraded to kernel version 2.6.17-1 (in edgy). No change... issue is still there:-(

[hunger (hunger)]

I found a solution! Adding the "button" module to the list of modules to unload fixes the issue for me.

[hunger (hunger)]

Maybe the button module could get added to the list of modules to unload by default? I think that might not harm other users and it will fix this issue for thinkpad users.

From what I heard this problem is still in gutsy.

Works for me for a while again. I'll close this bug.
