PC wakes from suspend prematurely

Tharbad · 2025-11-08 22:30:44

Hi,

In the last 2 weeks my desktop PC woke from suspend after a few hours. haven't changed any hardware.
PC should wake up only when I press the power button.

I've looked in the wiki:
* cat /proc/acpi/wakeup says only BXBR is enabled. I'm quiet sure it's the power button.
* I run

 sudo dmidecode -t system | grep -P '\tWake-up Type\: '

on 2 of the 3 times. It's

 Wake-up Type: PCI PME#

I googled:
* And found this: https://bbs.archlinux.org/viewtopic.php … 6#p2040926
* Where seth tells to add

pcie_port_pm=off pcie_pme=nomsi

* I searched again and found this: https://askubuntu.com/questions/1104219 … nomsi-mean and I don't understand how that solution can help

Kernel is zen. Didn't update in the last month.

kernel boot options:

options root=PARTUUID=4006b234-5749-4544-a963-1e57e55b0551 rw lsm=landlock,lockdown,yama,bpf processor.max_cstate=1 nvidia-drm.modeset=1

Also noticed that when in suspend computer doesn't turn off, fan still work.
I assume it's part of suspending to ram?

So here I am asking for help.

Please post the file as well as "lspci -nn"

I don't understand how that solution can help

The ubuntu thread talks about the unrelated "pci=noaer" and "pci=nomsi"
https://raw.githubusercontent.com/torva … meters.txt

pcie_port_pm= [PCIE] PCIe port power management handling:
off Disable power management of all PCIe ports
force Forcibly enable power management of all PCIe ports
pcie_pme= [PCIE,PM] Native PCIe PME signaling options:
nomsi Do not use MSI for native PCIe PME signaling (this makes
all PCIe root ports use INTx for all services).

Whether that's the case here or there IDK, there's a link at the end to another thread where the BIOS needed to be conviced that it's totally running windows.

on 2 of the 3 times

What's the other time?

* I run

Does the journal record any reason for the wakeup?

Ceterum censeo: If there's a parallel windows, see the 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

1 out 3: Didn't check. Can't tell.

No windows. Blasphemy

Nothing i journal, just a normal wakeup. Looked after the 2nd time only.
Will look again if it happens again.

If you disable the event, does the power button indeed no longer allow you to wake the system?
(You could enable XHC0 and PS2K to allow you to wake the system still)

I can try but it's not optimal, the mouse is moved and keyboard is touched when the pc is off.
That's why I disabled both of them.

They're just meant as backup in case BXBR actually controls the power button - it's enough to enable them, disable BXBR, suspend and see whether you can still wake w/ the power button.
If yes, you could disable BXBR as well.

BXBR isn't the power button. Will disable it. Tempfiles?

https://wiki.archlinux.org/title/System … rary_files is a way to automatically set this but pay attention whether the value gets reset w/ wakeups.
