Shutdown hangs on "Reached target System Power Off"

[marosh-reset]

Hi everyone!

Occasionally (~20 % probability), my laptop (system info) hangs on shutdown or reboot with the messages as seen here (sorry for the photo, I can’t find out where this is logged): https://imgshare.cc/nby36jat

I need to kill the machine by long pressing the power button, which is obviously bad. REISUB is set up and generally working, but unfortunately not in this scenario.

sudo journalctl -b -1 after such an occasion (I cut off the content before I triggered the restart).

What do?
Regards

I cannot imagine that you are all completely clueless, so … is something wrong with my post?
Any more specific info I can provide?

Nothing’s wrong with your post, - we’re all just regular people here with jobs and lives. If we can help, we will. Insulting us won’t make that happen any faster.

Shut Down Disks on Shutdown?

Hey! Welcome to the forums! From experience of the same issue, this is a hardware config requirement. Take a look at your BIOS/UEFI settings, - and you should find ErP. Enable it. You may need to adjust settings based on what kind of hardware you have, but start with S4+S5. Lots of resources on the web for what and how ErP works, but start with your own manufacturer’s documentation. Good luck

I’m sorry, I did not mean this insulting at all! Sorry that it came across as such!

I have been lurking the forums here for a few months now and my impression is that usually help comes along quite quickly, and very competently, so I was genuinely thinking “my problem can’t be too hard for them, so either there’s something wrong with my post or it got lost in their feed”. Either way I hoped to help it by bumping the post.

Thanks for the link, I’ll look into my BIOS settings.

No luck with the BIOS; there is no ErP setting. And it is not that some component is still on after shutdown … the shutdown process gets stuck somehow; it would hang for hours, updating the “task blocked for more than xxx seconds” message every two minutes or so until I force-shut it off.

Does reboot work?

[marosh-reset]

Yes – I don’t have the feeling that it makes a difference whether I shut down or reboot. It happens in both cases, but not always, maybe 20 % probability.

Fully understand it’s hanging before shutdown, and this is usually a kernel issue looking at your pic. Upgrade to 6.15.6-Arch1-1

As for ErP/EuP
It’s usually in Advanced settings, I can’t say more without knowing the model of your motherboard, look for S4 or S5, - set it to either of those. S5 is the equivalent of a full power off with just trickle power to the power button. S4 includes hibernation/suspend support. Set it to enabled.

Upgrade to 6.15.6-Arch1-1

Well that did the trick! I rebooted about 12 times without issues. Oh man, easy fix. Thanks!

I told myself that touching the kernel is forbidden because using the lts version is @dalto’s #1 issue-avoidance rule (How to run a stress-free EndeavourOS). Well, I’ll stick with stable for now. The whole desktop even feels faster and more responsive.

Thanks a lot!
