NVIDIA suspend fails with nv_pmops_suspend() returns -5 when Haruna is

Hi everyone,

I'm experiencing an issue with suspend on my ASUS VivoBook X510UF running Arch Linux.

Suspend works normally in most situations, but it consistently fails when Haruna is open playing a video (even if the video is paused). If I close the laptop lid while Haruna is still open, the system attempts to suspend but immediately resumes and prints kernel messages on the console.

If I close Haruna first, suspend works perfectly.

The same is true if I'm only using a web browser or editing documents—closing the lid suspends the laptop without any issues.

Laptop: ASUS VivoBook S15 X510UF
CPU: Intel Core i5-8250U
iGPU: Intel UHD Graphics 620
dGPU: NVIDIA GeForce MX130 (Optimus)
RAM: 16 GB
Arch Linux
Kernel: 7.1.3-arch2-1
KDE Plasma 6.7.3
Wayland
NVIDIA Driver: 580.173.02

$ cat /sys/power/mem_sleep
s2idle [deep]

$ systemctl status nvidia-suspend.service

$ systemctl status nvidia-resume.service

$ systemctl status nvidia-hibernate.service
enabled

$ glxinfo -B

OpenGL renderer string: Mesa Intel(R) UHD Graphics 620

$ prime-run glxinfo -B

OpenGL renderer string: NVIDIA GeForce MX130/PCIe/SSE2

Error shown on the console

When closing the lid while Haruna is open, I get the following messages:

NVRM: GPU 0000:01:00.0: PreserveVideoMemoryAllocations module parameter is set.

nvidia 0000:01:00.0: PM: pci_pm_suspend(): nv_pmops_suspend() returns -5

PM: failed to suspend async: error -5

PM: Some devices failed to suspend, or early wake event detected

After that, the system immediately resumes instead of entering suspend.

Questions
Is this a known issue with NVIDIA driver 580.xx?
Could NVreg_PreserveVideoMemoryAllocations=1 be causing this?
Has anyone experienced the same problem with Haruna or other MPV-based players on Optimus laptops?

Any suggestions or things I should test would be appreciated.

Thanks!

Re: NVIDIA suspend fails with nv_pmops_suspend() returns -5 when Haruna is

Does haruna decode on the nvidia GPU?
Do you have the same problem w/ mpv itself?

You'd typically get this if the userspace services for the VRAM preservation are not running or fail - anything interesting about those services (or userspace in general) in the system journal?

I checked with nvidia-smi while Haruna is playing a video. Haruna does not appear in the process list and only kwin_wayland is using the NVIDIA GPU (2 MiB). The same is true while watching YouTube in my browser. It looks like video playback is not using the NVIDIA GPU directly.


I also discovered that the issue is not specific to Haruna. I can reproduce the same suspend failure while watching YouTube in my browser. If I close the video player/browser before closing the lid, suspend works normally.

Re: NVIDIA suspend fails with nv_pmops_suspend() returns -5 when Haruna is

Ok, so somehow™ playing a video on the IGP makes the nvidia VRAM preservation service fail… wtf?

In doubt post your complete system journal for the boot after such failure

sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

I intentionally triggered the error and captured the boot journal as requested.

Here is the link to the journal:

And here are the specific errors that occurred:

Re: NVIDIA suspend fails with nv_pmops_suspend() returns -5 when Haruna is

The journal covers only 80s and no sleep attempt, did you reboot after the sleep attempt failed? Why?
You'd have to access the journal of the previous boot (… -b -1) then.

I had to reboot because when this error occurs, the system completely freezes. The screen goes entirely black, the laptop gets very hot, and the cooling fans spin up to 100%. The system becomes completely unresponsive, and the only way to recover or restart is to perform a hard reset by holding down the power button.

I reproduced the crash and pulled the journal from the previous boot using -b -1.

https://wiki.archlinux.org/title/Hardwa … ing_VA-API

The VRAM userspace sleep process triggers a nullptr in nvidia_uvm (cuda/nvdec related, so the video thing makes sense) and that prevents the GPU from entering the the sleep.
From what I can tell what's then causing some trouble is the webcam, at least it flares up on the fast-ish re-connect.

The question is whether we can get VAAPI completely away from nvdec and whether that protects the UVM module.
Brute-force solution would be to blacklist that, but it would break anything CUDA related.

Re: NVIDIA suspend fails with nv_pmops_suspend() returns -5 when Haruna is

I set LIBVA_DRIVER_NAME=iHD as discussed and rebooted. The system still fails to suspend, but the behavior has changed. Instead of a total black screen lockup with 100% fan speed, the suspend process now aborts, and I get a kernel output on the screen with two distinct issues.

1. NVIDIA power management failure:
The suspend is aborted by the NVIDIA driver returning a -5 error. It complains about the power management interface:

NVRM: GPU 0000:01:00.0: PreserveVideoMemoryAllocations module parameter is set. System Power Management attempted without driver procfs suspend interface. Please refer to the 'Configuring Power Management' section in the driver README.
nvidia 0000:01:00.0: PM: pci_pm_suspend(): nv_pmops_suspend [nvidia] returns -5
nvidia 0000:01:00.0: PM: dpm_run_callback(): pci_pm_suspend returns -5
PM: Some devices failed to suspend, or early wake event detected

Immediately after this failure, the USB webcam (13d3:5a07) goes into an infinite loop of disconnecting and reconnecting.

2. A FUSE process blocking the freeze:
On another attempt, the user space processes refused to freeze entirely due to what looks like a hanging FUSE filesystem:

Freezing user space processes failed after 20.004 seconds (1 tasks refusing to freeze, wq_busy=0):
Call Trace:
<TASK>
...
fuse_simple_request
fuse_lookup_name
...
vfs_statx

Regarding the NVIDIA error, should I enable the nvidia-suspend.service (and related hibernate/resume services) to fix the NVRM procfs issue, or is this still a symptom of the UVM module conflict?

Also, regarding the webcam errors: the camera has a hardware issue with its ribbon cable. I previously disabled it on the system level (though I honestly don't remember the exact method or commands I used to do it). That probably explains why it falls into an infinite disconnect/reconnect loop when the system crashes.

Re: NVIDIA suspend fails with nv_pmops_suspend() returns -5 when Haruna is

Do you have the journal from that boot?
The nvidia-suspend.service was enabled, but failed (apparently because of the nvidia_uvm crash) - no idea why the kioworker freaks out (you'd also want to check what fuse mounts you actually hold) but it looks like it's a result of the hiccup-wakeup as well.

Can you disable the webcam in the BIOS/UEFI settings?

Next step would be to flat out blacklist nvidia_uvm to at least see whether it's the origin of the troubles or just another symptom.
Why mpv (what about vlc?) would dog around on the nvidia GPU when VAPPI is explicitly directed towards iHD is kinda beyond me hmm
