PCIe Bus Error, Bad DLLP etc.


After installing a new SSD drive to my computer, Linux terminal is flooded with PCIe Bus Errors:

PCIe Bus Error: severity=Corrected ... [7] Bad DLLP.

I was able to find out that the device causing the problem is actually my GPU (Radeon RX580). The problem occurs with my Arch install but with live-cd also.

I'm able to get rid of error messages by adding kernel parameter pci=nommconf . But the real problem is that now the computer gradually slows down when doing stuff with it, playing Doom for example. Frame start decreasing after 15 minutes of playing, and strange rattling sound starts coming from my BT headset. This is not an overheating issue, I've ensured that.

Does anyone have any advice on what to do, or is it RMA-time for the motherboard?

Some specs:
Asrock AB350n itx
AMD Ryzen 1600
Sapphire Radeon RX580 Pulse
Samsung EVO960 nvme-drive and EVO860 sata ssd drive.

Edit: Tried with separate GPU, same error messages keep coming

According to … /118977/36 "pcie_aspm=off" might at least mitigate the issue.
