    Hello,

    I get a lot of PCIe port errors although they are corrected by the bus protocol thanks to (error correction) this makes me nervous. See logs below.

    I already disassembled the bolt, and tested with default settings from BIOS/UEFI and with no devices in NGFF/M2 slots connected just booting from network(grml) or eMMC(focal).

    The referred device is 0000:00:01.6: which is according to lspci:
    00:01.6 PCI bridge: Advanced Micro Devices, Inc. [AMD] Raven/Raven2 PCIe GPP Bridge [6:0]

    I have installed an Ubuntu Focal on NVMe and eMMC and when network booting I have a grml booted.
    Is someone seeing this too? What might be the cause? Any hints?
    Might this be a potential support case?

    best regards

    @ccs_hello thanks for pointing me to this link, which post number you mean in specific? I do not see a direct relation, as PCIe bus 6 is not mentioned by the logs above. The logs are mentioning bus 0 with it' PCIe bridges.

    The PCIe bridges are high likely the endpoints for some of the attached hardware at the M.2 connectors, according to #12 in your mentioned thread.
    I get those messages, too, when no hardware is connected to those M.2 ports. Thats why I am confused by your answer.

    Oh, yes thanks, I wrote that in my initial post. Are you seeing this, too? Or do you have ideas how to fix it?

    No, I do not have the PCIe bus error issues.
    As you can see in my earlier picture, that 6:0 has all 3 M.2 slots' PCIe buses as well as Realtel Ethernet controller.

    BTW, do you see the same issues if using a different OS?
