I recently installed manjaro and noticed that my CPU stays at around 95-98% usage and it is mainly because of this process “irq/124-aerdrv”. I don’t know how to solve this issue so if you could help I would be very grateful. I am using a dualcore intel i5 7th gen cpu and an nVidia 920MX. I am also on a laptop.
can you boot on USB live manjaro
open a terminal
inxi -Fza sudo journalctl -b0 -p4
I got the results but i can’t copy paste them here so here they are on paste bin
tri with add on boot kernel :
“pci=noaer” or “pci=nomsi”
I tried both but it still didn’t work. Any other solutions?
try to update your UEFI
How and from where. Sorry I am new to this but afaik i can’t find the bios file nessecary for the update so if you could help that would be awesome
Should be this one:
There is first the Windows one, but it is a exe and can’t be used on linux. You will need to download the second one, extract the zip file to a flash drive with fat32 formated and boot into your UEFI. There you should be able to update the UEFI by grabing the file at the menu.
To update the BIOS:
- Verify the Notebook PC’s exact model then download the latest BIOS file for your model from the ASUS website.
- Save a copy of the downloaded BIOS file to a flash disk drive.
- Connect your flash disk drive to your Notebook PC.
- Restart your Notebook PC then access the BIOS settings.
- From the BIOS menu, select Advanced > ASUS EZ Flash 3 Utility, then press ENTER.
I updated it. Nothing changed. I still have that process running. I tried the “pci=noaer” and “pci=nomsi”, still nothing. I even tried a “pci=nommconf”. Nothing changes and my CPU is still at a 97% usage because of that process. Any other suggestions?

this also appeared when i logged the errors with the second command the first guy mentioned
Can you switch to an LTS kernel like 5.4 and check if the problem persists?
Also, I have had issues with nouveau driver and CPU usage spikes. I had to switch to the proprietary driver to solve the issue.
OMG THIS WORKED. I installed it and then I added the line is needed like pci=noaer, pci=nomsi and pci=nommconf. After that I rebooted and the process is GONE. THANK YOU EVERYBODY
