I am running Fedora 30 64-bit on an AMD Ryzen 2700U and I've noticed that journalctl gets a lot of messages about PCI bus errors (all identical).

What might be causing this and what does it mean by BadTLP and BadDLLP?

  • See here for "Bad TLP" and some discussion. A "DLLP" is a data link layer packet.
