Re: Laptop randomly unable to wake from suspend state

Hey all!
This problem seems to be back since updating to 5.17.1
Only difference is that there are no logs whatsoever to go by. It seems more consistent as well, before I could go a couple of days with working suspend, now it seem like every morning I have to hard reset the laptop.
Anyone else experiencing this regression?

KInd regards!

Re: Laptop randomly unable to wake from suspend state

I can confirm on my T495 as well: Suspend/resume was always a bit unstable, but now I can absolutely never resume from suspend on kernel 5.17.1. Both when docked and when on battery. USB comes online (keyboard, mouse lights up), Display and Ethernet doesn't.

Re: Laptop randomly unable to wake from suspend state

I had the same problem on Lenovo Legion 5 15ARH05H, I started using the nouveau driver and the problem disappeared.

Probably not the same issue, but https://download.nvidia.com/XFree86/Lin … ement.html ?

Same here, unable to resume from suspend since last kernel update.

Cool that you found the exact commit!! Incredible what one line of code can do
How did you even get to that post?

This time I'm not going to bother patching and building my own kernel, I downgraded to 5.16 and it is suspending just fine.
I guess 5.18 will fix things?

I had the same problem on Lenovo Legion 5 15ARH05H, I started using the nouveau driver and the problem disappeared.

Hmm, are we talking about the same issue? I don't think this is graphics related, but what do I know...
What I do know is that nouveau has terrible screentearing on my T495 setup, so I want to stick to amdgpu.

Re: Laptop randomly unable to wake from suspend state

https://git.kernel.org/pub/scm/linux/ke … =v5.18-rc1

^When I look at the source of 5.18 mainline, this if statement at line 573 (before the flush cpu cache) is still present.

I guess that means that we won't be able to use 5.18 either?

I'm sorry, I thought that fixed the problem, but it really didn't. I managed to avoid this problem by turning off the setting Dim Screen (off) and Screen Blank (Never). And I don't know if it will work tomorrow or in an hour. Also a problem with the brightness of the keyboard backlight, but I do not write a bug report because it is hopeless, no one will fix it

my keyboard backlight works but changes brightness level arbitrarily after waking up. also, my laptop is legion 5 (with amd), not legion 7i.

Re: Laptop randomly unable to wake from suspend state

If you can control it (?, https://wiki.archlinux.org/title/Keyboard_backlight ) you could use some sleep hooks to re/store the value.
As it's rather weird for this to alter during an S3, teh standard question is whether there's a parallel OS (window) and then see the 3rd link below…

Wasn't me who found it the commit. Just googled the commit-id that was reported as offending and found the submission to revert it :-)

Ah fantastic that rc2 fixes this! Then I can get back up-to-date.
Thanks for the heads up!

Re: Laptop randomly unable to wake from suspend state

Confirmed fix is also in 5.17.3, which works for me!

Re: Laptop randomly unable to wake from suspend state

What is currently the best workaround for this issue?

I reverted to 5.17.3-arch1-1. It worked for a couple of weeks, but I've had two freezes in the last day.

Has the mainline (5.18-rc4, as I write) worked?
