AER
AER (Advanced Error Reporting) shows a correctable error on device 1c.0. According to sudo lspci -tv the misbehaving device might be your wireless 3165 card. Check to make sure you have the latest driver and firmware for this device.
Otherwise, if you see no outward signs of operational issues, and after scrutinizing /var/log/syslog*, you can do this to quiet the noise...
sudo -H gedit /etc/default/grub # edit this file
Locate the string "quiet splash" and change it to "quiet splash pci=noaer".
sudo update-grub # update GRUB
reboot # reboot the computer
