[SOLVED] Laptop cant wake up from suspend since Linux 6.16

seth · 2025-08-22 19:55:30

@Nicothekiller, only boot the multi-user.target, 2nd link below, along "nomodeset". Send the system to sleep, wakeup, pray that there's output on the console…
@alba4k, see #14, specifically

==> what happened between ago 18 17:58:53 and ago 18 20:47:29 ?

Have you ever tried a cold reboot or even resetting the CMOS?

Nothing that I'm aware of

Just tried that, doesn't really seem to have helped

Can you reproduce the issue without the nvidia module loaded?

coder2195 · 2025-08-29 21:14:17

6.16.4 was supposed to fix the issue but it did not for my g15

Any luck for anyone else?

seth · 2025-08-29 21:25:46

Afaict we've never seen any journal from your failed wake-ups, let alone anything suggesting it to be the xhci issue you're likel referring to

coder2195 · 2025-08-30 14:34:09

Here is the logs from laptop lid closing to the forced reboot I performed by holding power button

I dont think there is any registration of a wakeup call like spamming my keyboard or the touchpad

reboot I performed by holding power button

Avoid that at all costs, the OP suggest to be able to reboot w/ the https://wiki.archlinux.org/title/Keyboa … el_(SysRq) - this doesn't work on your system (nb. yo've to explicitly enable the feature first!)

(remove the nvidia packages to run the system on nouveau - can you wake from the suspend?)

There are some solution ? i'm with errors in suspention in my dell g15 5520 after kernel upgrade. black screen on resume, need to use sysreq reisub to reboot the system.

Then please post your complete system journal for the previous boot:

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

linuxzinho · 2025-08-31 21:04:04

Here is my log: https://0x0.st/KHvT.txt

I booted into the system, logged in as my user, and then suspended the computer without doing anything else.
The screen went black, so I used the ReisUB command to reboot. I noticed that after the last line, 's2idle,' nothing else was recorded.

nb. this isn't a "command", you're supposed to type "sysqr+r", "sysqr+e", "sysqr+i", "sysqr+s", "sysqr+u", "sysqr+b" and probably give every step some seconds to be sure.
Notably the "S" and the "U" will sync and umount all partitions which would be the step to make sure the journal gets written to disk.

Iff this is what you did and since the kernel resumed (otherwise the "B" would not have rebooted the system) the most likely troublemaker would be the nvme, https://bbs.archlinux.org/viewtopic.php … 6#p2257316

Yes, I used the REISUB sequence correctly. I also tested placing the kernel arguments nvme_core.default_ps_max_latency_us=0 pcie_aspm=off iommu=soft in my kernel boot, but it didn't work.

Something I noticed is that the notebook doesn't appear to be truly suspending. After I try to suspend it, my screen goes black, but the keyboard backlight doesn't turn off. When I press a key, like caps lock, the light responds instantly, without the usual delay from waking up. Is this normal when a system suspends correctly?

seth · 2025-09-02 07:09:46

Hardly.
s2idle is your only option?

Or can you maybe even disable the GPU in the UEIF settings (integrated graphics only)

https://github.com/intel/ipu6-drivers/issues/381

I found this issue related to ipu6-drivers. I'm not sure if my notebook uses them, but if it does, I will try removing them and testing the suspend functionality. If that works, I'll post the results here and link to this thread in T0mK0's GitHub issue. Otherwise, to be certain, I will downgrade my system to kernel 6.15 and see if that definitively solves the problem.

Thanks, this solved my laptop's suspend problem with the intel-ipu6 module.
Had same problem: 6.15.9 - everything is fine, 6.16.x - breaks suspend.
After upgrading my kernel to 6.16.4, I removed the intel-ipu6 module:

sudo dkms remove ipu6-drivers/0.0.0

Suspend started working again after a reboot.

gromit · 2025-09-05 09:52:07

I skimmed through the linked issue, but I seems like no one has bisected it yet to the commit that actually broke the suspend feature.

Are you confident to do the bisection on your own or do you need some help?
If you want we could also provide you with pre-built kernel images for you to test (which greatly speeds up the test time) a

Good info to get you started is:

Reference to an endevaorOS post about ipu6, pretty sure it should be included by default now. Running the command does indeed indicate it is built in.

linuxzinho · 2025-09-08 17:53:18

Hello, my system is not currently using ipu6 and I had an issue with the suspension of my notebook. I changed my kernel to the LTS version, 6.12.45-1-lts, and the suspension works again. As I use suspension a lot, I changed my kernel to a version that does not cause problems.

I would like the pre-built kernel images for bisect. This week I don't have time to test, but I can surely test more thoroughly next week.

jmacg · 2025-09-13 07:00:25

I have the same issue. Could be fixed in 6.17? https://www.phoronix.com/news/Linux-6.1 … tion-FIxes

seth · 2025-09-13 15:39:49

That article references a bug in hibernation (S4) specifically while the affected users are facing problems w/ S3 and s2idle - it's not very likely that the patches mentioned there will fix anything about the situation ITT
There's a bunch of bisection kernels and 6.16 rc version in https://pkgbuild.com//~gromit/linux-bisection-kernels/ which you can maybe already use to narrow in on the bad patch.

Nicothekiller · 2025-09-20 21:40:09

Sorry for taking so long to reply, i was occupied with some stuff lately. I tried the ipu6 thing. The command indicates that ipu6 "is not located in the DKMS tree".

Since ipu6 isn't it, i will try to live boot from a USB with a recent kernel to see if it still happens there. Maybe ill try to bisect tomorrow if I have the time.

I tried to boot with the latest arch Linux install ISO and the fedora rawhide net install. Arch was using the 6.16.4 kernel and fedora was using a 6.17 rc kernel. I checked the arch Linux ISO and it wasn't using the proprietary nivida modules, it was using noveau (checked just to make sure). The issue happens on both kernels on both distro installers. Based on this info, this should confirm its not an nvidia thing, and its most likely a kernel issue.

Nicothekiller · 2025-11-09 16:15:45

In the end, I was so occupied these last few months that I wasn't able find the time to bisect the issue. But it seems to be fixed now as of Linux 6.17.7-arch1-1! (6.17.4 if i remember correctly was the last version i tested before this one. It was still broken.)

Thanks so much to everyone that helped triage the issue, even if nothing of value was found.

On that note, I now have a new issue, where in performance mode with power-profile-daemon the fans instantly go to max. Considering this is a gaming laptop, its quite noticeable. This behavior is new.

Regardless, I will mark this issue as fixed now. If you had this issue, maybe you can use the regular kernel again. Still, keep the LTS kernel installed. It saved my ass for moths until this got fixed. You never know when it will be useful.

My system still reboots after a couple seconds of suspension.. I guess I will open a separate thread
