I have Ubunuu 16.10 (although the same happened on 16.04) on a dual boot with Windows 10. I noticed some time ago that my kern.log file was getting pretty big (10GB or more) so I decided to check it. The same error seems to be repeating every second or less:

Dec 19 17:31:01 andrew kernel: [   99.027473] pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID)

I have tried adding to the grub pci=nomsi and pci=noaer but it keeps popping up. I am using a ASUS Laptop with an Nvidia Geforce 920M. Maybe that's the reason?

I believe this may be due to PCIe Active State Power Management that is transitioning the link to a lower power state and maybe causing the device to trigger these errors. I believe the device in question is the Sunrise Point-LP PCI Express Root Port.

Try using the pcie_aspm=off boot parameter to see if this stops the messages. Note that this will increase the power consumption of your machine as it disables the power savings.

Try these steps:

1. sudo gedit /etc/default/grub


2. 
   

   Edit grub. Add pci=noaer at the end of GRUB_CMDLINE_LINUX_DEFAULT. Line will be like this:

   
   
   

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"

   
   



3. sudo update-grub



4. Reboot now

:) Enjoy.

I installed Ubuntu 18.04 today and I noticed the same problem. I've just installed that package and problem has been solved.

sudo apt-get install busybox-syslogd

Check log files size and do empty large files:

ls -s -S /var/log

result:

total 4352668

4021088 syslog                 32 wtmp                  4 gdm3

 329168 kern.log               24 Xorg.0.log            4 hp

   1776 dpkg.log               20 Xorg.1.log            4 installer

     40 lastlog                20 Xorg.0.log.old        4 journal

and do:

cd /var/log

sudo su

$ > syslog

$ > kern.log

Then, to make sure, let follow this answer above https://askubuntu.com/a/1019225/725320

In case you can't boot into Ubuntu and get stuck with these logs in your screen (same as me):

• Use Recovery Mode to get root shell
  


• Do empty large log files


• Boot into Ubuntu, install busybox-syslogd and update grub config

I had the same problem, but the solution was to add pci=nomsi to /etc/default/grub file. Perform the following edit:

before:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

after:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

And save the settings:

sudo update-grub
