I recently upgraded Ubuntu 16.04 to 18.04 on my PC (with Nvidia GeForce GTX 1080 Ti GPU) and ever since my file system has been building up from these huge log-files. Every time I shut down my computer I get an endless number of pcieport-messages until some time the PC shuts itself down.

Yesterday I left my machine on for the night and when I came back to it there was a notification that disk space is all used up, that is /dev/sda1 was in 100% use. I managed to find this out via du-command and pinpointed the problem to log files in /var/log/-folder, which contained log-files of more than 350GB.

Currently, the log files are building up again and now they take up space approximately 150GB. The log files that are causing the problem are: syslog.1, syslog and kern.log

My question is: What is causing this problem and how to fix it?

I have listed below information about my system and few lines from the log files. I will remove them again, but endlessly removing them does not seem the best long term solution.

I got the problem solved (I think) already by using the instructions here:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521173

WORKAROUND: add pci=noaer to your kernel command line:

(1) edit /etc/default/grub and and add pci=noaer to the line starting with GRUB_CMDLINE_LINUX_DEFAULT. It will look like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

(2) run "sudo update-grub"

(3) reboot

After implementing these steps, I don't get the pcieport-messages anymore after shutting down my system and the log files stopped hugely growing in size.

However, I don't know if this fixed the root cause of the error-messages...
