I bought recently a computer and installed ubuntu but get this error when ubuntu is booting

[   91.167119] pcieport 0000:00:1c.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e0(Receiver ID)

[   91.167122] pcieport 0000:00:1c.0:   device [8086:9d14] error status/mask=00000001/00002000

What is it?

How to fix it?

Answer 1

I had the same PCIe BusError messages in boot and spamming my logs on Asus x550v (Skylake cpu).

Try this:

Current workaround is to add pci=noaer 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

from Workaround here

note: If pci=noaer doesnt work try use pci-nomsi instead.
