I can't suspend my PC anymore

Hi there.

I have a situation where I haven't updated my Arch setup for a month,
today, when I tried to suspend my computer via sleep, my computer just started making loud noises from the fans while the screen was off.

Re: I can't suspend my PC anymore

Is it desktop or laptop? What model is it? Do you also have Windows installed on it?

Did you read this?

And post full output of command 'sudo journalctl -b-n' where 'n' is number of post ago in [code][/code] tags.

Re: I can't suspend my PC anymore

I have same issue. Suspend is broken with kernel 6.17.1. Workaround is to downgrade back to 6.16.10

Re: I can't suspend my PC anymore

I have same issue. Suspend is broken with kernel 6.17.1. Workaround is to downgrade back to 6.16.10

As a beginner tried to fix this problem for like several days. Was tinkering grub config, nvidia one, logind, sleep, reinstalling drivers and other ways - none had any positive effect. And now it got fixed by simple downgrading (quick reminder - don't forget to downgrade your GPU drivers likewise). Feeling kinda dumb tbh...
Thanks a lot for the hint!
