Hi there. I have this process using nearly all my cpu resources and i cannot make it stop. I have read to make some settings in bios. i was playing around a while but nothing changed.
This process is using nearly 90% of my cpu

Could you share that while it runs at 90% ?

cat /proc/interrupts 

Thanks for your reply. When i opened Top it was shortly on 95%

Hi @kubwit,

Have you tried with a different kernel?

1 Like

Thanks @Mirdarthos . I am regularily updating without tweaking by my own. So yes. Kernels since october last year. This is the period since i have issues with having my system accidently overloaded and unusable. I am using this installation on the same machine for a some years now. Before i never had this issue.

Oh. Well, if you have, then

Ok that one… I would try to add acpi=off to the kernel parameter to work around. But first check what could be the issue.

Run this service:

sudo systemctl enable --now acpid

and then run:

acpi_listen  

It will now listen to all ACPI Events. There is probably a hint what device/connector etc. produces a lot of interrupts here.

Here is a list of all the factors that can cause the problem:

  1. ACPI Battery – Monitoring battery status and charging events.
  2. ACPI Temperature Sensors – Temperature monitoring and fan speed control.
  3. Fan Control – Fan status and adjustment interrupts.
  4. Power Management – CPU throttling or power state transitions.
  5. Sleep/Standby Mode – Transitions between different power states.
  6. Power Button and Sleep Button – Events triggered by pressing the power or sleep buttons.
  7. PCI Devices and Peripherals – ACPI events from PCI-connected devices (e.g., network adapters, USB controllers).
  8. ACPI Hotkeys – Volume and brightness adjustment hotkeys.
  9. IRQ Management – Interrupt request (IRQ) handling and device communication.
  10. External Devices – Events from external devices (e.g., docking stations, external drives).

Yes. I also modified bios acpi settings but they didn’t change anything

Thanks @megavolt .

I also tried to check with chatgpt. But there was no result.
I tried acpid with this result

acpi_listen                                                                       ξ‚² INT ✘ ξ‚² 42s ο‰’

Nothing was shown up only my manual keyboard test

I also diasbled all acpi in bios.

Where can i add the Kernel parameter? In Grub?
like this ?

linux /boot/vmlinuz-xxxxx root=UUID=xxxxxxxx ro quiet splash acpi=off

Thanks in advance

File: /etc/default/grub
Add/Modify: GRUB_CMDLINE_LINUX_DEFAULT="<some existing params> acpi=off"
Then run sudo update-grub
Reboot now.

@megavolt Thanks again. But this ends with a black screen on boot. I tried it already with β€˜e’ on boot to add it not permanently. So i don’t know what this could be.
I checked also my laptop where i have the same installation. There i cannot see any Irq/9-acpi process

$ grep . -r /sys/firmware/acpi/interrupts/

Look for big numbers and try masking the associated interrupt(s). E.g.

$ echo "mask" | sudo tee -a /sys/firmware/acpi/interrupts/gpe17

If that fixes your problem then use one of the recipes in this link to apply it at boot;

Great. That’s it!! I will go for this. Thanks for showng the way. They say it is because of faulty Hardware.

Thanks to all for your time.
