https://askubuntu.com/questions/771899/pcie-bus-error-severity-corrected The workaround: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521173 <code>WORKAROUND: add pci=noaer (or pci=nomsi) 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</code>
