Hi,

i have an uptime of 2 days, my system log is full of:

Jul 5 16:11:45 BackTower kernel: pcieport 0000:00:1c.6: AER: Correctable error message received from 0000:00:1c.6

the pcieport 0000:00:1c.6 lines up with:

I am not sure if this is the "best practices" method, but I had this exact same error with log spam and setting pcie_aspm=off fixed it for me. On the Main page, click on your boot device ("Internal Boot" or "Boot(Flash)", etc), then under the Boot Parameters tab in the Power Management section you can set that with a toggle. Then just reboot.

Yep, this is the first option you should try; there's another one if this one doesn't work, but it only suppresses the errors.
