35 GB/day of "PCIe Bus Error: severity=Corrected, type=Data Link Layer..." in syslog

• Ubuntu 20.04.4 LTS
• Dell XPS 8940
• latest BIOS 2.4.0

New install, and system seems to be working fine, but I have 35 gigs/day of syslog error messages like:

Here is the output of the following commands

sudo lspci -nn
sudo lspci -tv
sudo lshw -C network
sudo sysctl vm.swappiness
inxi -Fxxxrz
sudo lspci -s 00:01.0 -vvv

(added lspci -s 00:01.0 -vvv output)

Thanks for any help you can give. Cheers.

P.S.

I had added this one line to /etc/modprobe.d/alsa-base.conf

# apparently after power saving shuts down the audio, the next time it turns on
# it will audibly pop. Turn off shutting down the audio to prevent the popping.
# see
options snd-hda-intel power_save=0 power_save_controller=N

It looks like your Nvidia card is causing the syslog problem.

00:01.0 PCI bridge [0604]: Intel Corporation Device [8086:4c01] (rev 01)

Try Nvidia 510.54. Try a different video card, if you can get access to one.

To quiet the syslog noise, do this...

sudo -H gedit /etc/default/grub # edit this file

Find:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Change it to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

Save the file.

sudo update-grub # update GRUB

reboot # reboot the computer

Update #1:

Fixed by turning off ASPM: pcie_aspm=off
