These errors are hardware related, and I probably shouldn't ignore them. Most likely from a PCIe card that isn't seated properly or something. Either way, I want to stop filling my Syslog with several gigs of this every day on a machine I don't care about. To suppress them, add the kernel parameter

append initrd=/bzroot pci=noaer

to your grub bootloader or, in the case of this system, syslinux configuration.
