systemd suspend works, but wake doesnt


Hey there,

I installed a new gentoo on my new ThinkPad X240. I installed systemd directly. I tried to configure my computer and currently have problems with supend. So far, when I type systemctrl suspend, my notebook switches to the supspend mode. The power button blinks slowly as expected in this mode. The problem is, I have no idea how to start my notebook again:

Neither key press, nor lid open-close nor pressing the power button has ANY effect. The only thing that helps is to press and hold the power button for same seconds to shutdown the notebook completly. The the notebook can be started again with another power button press, but it is a "fresh" reboot.

Where can I start to search for the problem. The is no log file for nothing hapening....

Any help is highly appreciated,
kind regards,
curator

The following thread may be reflective of the issue you describe

https://lists.fedoraproject.org/pipe...ry/446239.html

Here's an Ubuntu bug-report describing a suspend issue with the same hardware...

https://bugs.launchpad.net/ubuntu/+s...x/+bug/1304529

Perhaps upgrading the kernel will fix this?

Can your machine resume correctly if suspended using
Code:
echo mem > /sys/power/state
as described here?

*This might help eliminate kernel-related power management issues as the cause...

Hey, thanks for helping.

I would of course change my kernel (current 3.14.14), but you said I should first determine wheather the kernel is the reason.

Code:
echo mem > /sys/power/state
That does suspend, but also not resume.

Will it anyway help, or has it a chance to help, to switch kernel?

Is there anyway to debug that?

Your kernel is newer than the one mentioned in the Ubuntu bug report, so maybe there is another regression affecting you. It might pay to submit a bug report yourself.

Seems resonable, but its first time reporting a bug. Any, to be honest, I have no idea where to post the bug and, even more, I have no idea which data to add.

1) Is it a kernel bug? Or have I only configured the kernel incorrectly?
2) In case of a OS bug? Which data to append?

I have ne "ErrorLog" or similar......

Edit: Hey there, I switched to Kernel 3.17.1. No change :-(
