Re: systemd pci, 100% cpu [Solved]

I don't know why the grub file didn't change so i wrote directly on /boot/grub/grub.cfg and i added pci=noaer and it works fine now

Re: systemd pci, 100% cpu [Solved]

btw you have to manually run 'grub-mkconfig -o /boot/grub/grub.cfg' to update the file.
as said in /boot/grub/grub.cfg, you shouldn't edit it directly.

Why I run Arch? To "BTW I run Arch" the guy one grade younger.
And to let my siblings and cousins laugh at Arsch Linux...

Upload longer text output like this

Oh i thought just grub-mkconfig wrote directly on the file. Thanks

Re: systemd pci, 100% cpu [Solved]

@archqt, "pci=noaer" is a good workaround for this issue.  We hope to fix the kernel so the parameter will no longer be necessary.  Would you mind attaching the output of "sudo lspci -vvs00:1c.5"?  00:1c.5 is the Root Port that is logging the RxErr, and the device connected to that Root Port might be the cause of the problem.
