this indicates that your bios doesn’t use the “advanced error reporting” mechanism. nothing to worry, you could change your system by installing additional acpi-packages and try if that solves it. but there is a more common used way by ignoring the “AE”-reporting because it doesn’t harm anything.
to do so you’ll have to edit /etc/default/grub and add
pci=noaer
to the existing entries at
GRUB_CMDLINE_LINUX_DEFAULT="
you’ll need sudo rights to save it after editing.
then you’ll have to run
sudo mkinitcpio -P
sudo update-grub
and reboot.
