[SOLVED] Systemd-journald is eating all my CPU

I already tried to change grub config, adding "GRUB_CMDLINE_LINUX_DEFAULT="quiet pci=nomsi"" but didn't help. What can I do?

Re: [SOLVED] Systemd-journald is eating all my CPU

Something is spamming your journal with an error (and journald is not very good at dealing with this ... or at most other things) so look up your journal for the cause and fix that.

Re: [SOLVED] Systemd-journald is eating all my CPU

Log is pretty much all like this:

I'm still trying to figure out what is causing all ther spam.

Re: [SOLVED] Systemd-journald is eating all my CPU

What about the kernel ring buffer (AKA dmesg )?

Re: [SOLVED] Systemd-journald is eating all my CPU

Use code tags for log dumps.

See this thread and my post there.

As for possible causes, it's marginal hardware compatibility (there are known instances like certain NV GPUs with certain Intel CPUs) or (maybe) poor physical connection - use lspci to find out which device is "00:1c.5" and if it's some discrete PCIe card, pull it out and reinstall back.

And when did it start and why?

Re: [SOLVED] Systemd-journald is eating all my CPU

It started after a fresh system installation.
dmesg gives the same error:

 AER: Corrected error received: id=00e5 

Setting "pci=noaer" or "pci=nomsi" didn't help me at all.
lspci returns:

00:1c.5 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #6 (rev f1)

,but I really don't know how to proceed.

Re: [SOLVED] Systemd-journald is eating all my CPU

Errr.... no offense, but where did you set this? At least the AER messages should vanish from the journal?

Also "lspci -tv"?

Re: [SOLVED] Systemd-journald is eating all my CPU

I added a parameter to kernel boot modifying /etc/default/grub.
lspci -tv tells me the issue is with the wireless card, apparently:

Re: [SOLVED] Systemd-journald is eating all my CPU

Did you also grub-mkconfig afterwards?
Are the AER messages still there?
Do you use nouveau or the nvidia blob?

Re: [SOLVED] Systemd-journald is eating all my CPU

I just figured out I didn't run grub-mkconfig after modifying the grub line. pci=nomsi works perfectly.
Sorry guys for being so careless, and thanks everyone for the help and the support!
