Intermittent PCIe Bus Errors on startup (Arch Linux)

0
0

Since April when I built my computer with Arch Linux OS, I have been getting some errors that seem to point to the ASPM control of some USB 3.1 on my ASUS "ROG STRIX Z370-E GAMING" motherboard.

I either get 0, 1 or both of the following errors following journalctl, the errors seem to be totally random, as to whether or not the errors occur. I would like to point out that the ports currently work, but their power is not able to be modulated by the OS. (Although, Windows has no trouble.)

My attempts at troubleshooting have led me to disable the affected USB ports in the BIOS, which fixes the problems. But I would obviously like the USB ports to work.

Below is some diagnostic information. I've also bolded the relevant info.

journalctl -xb -p3 [timestamp and "archlinux kernel" removed for brevity]
