    Angry PCIe AER problems Fedora 27

    Hi there,

    I'm having some trouble with my Fedora 27 system. Maybe some of you have some more info.

    Simply speaking, the advanced error reporting is flooding my system log with messages of the form:

    [   139.027473] pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID)
    [   139.027474] pcieport 0000:00:1c.5:   device [8086:9d15] error status/mask=00000001/00002000
    [   139.027475] pcieport 0000:00:1c.5:    [ 0] Receiver Error        
    [   139.027479] pcieport 0000:00:1c.5: AER: Corrected error received: id=00e5
    [   139.027826] pcieport 0000:00:1c.5: can't find device of ID00e5
    [   139.027887] pcieport 0000:00:1c.5: AER: Multiple Corrected error received: id=00e5
    I am aware (a little, at least) of what AER is and what its aim is (should be..). I'm also aware of many people filling many forum threads in regard of this, but I am writing now (hoping) to get some updated information, and maybe give other info back to the community.
    - Are Fedora developers aware about this? Do you think I should get in touch to give testing ground? (How/where do I do that?)
    - Does ANYONE know why this happens (or when)? Maybe there are simple workarounds (not implying the AER system being disabled with pci=noaer, which seems to me a little bit simplistic).
    - Does anyone know the bureaucratic stuff I would need to eventually have Intel informed of this problem? We all know their policy (use Microsoft? Welcome. Otherwise, get f*cked), but they can't even ignore a problem affecting a new platform like Kaby Lake R, on a brand new OS.

    In the possibility of this being useful to someone, I am running on a Dell Inspiron 5570 (i7-8550u, AMD 530, etc.).

    Thank you all,

    I know nothing about AER but if you want to let the developers know that there is a bug or problem with an aspect of Fedora here is a good Fedora wiki that will explain the process in detail: https://fedoraproject.org/wiki/How_to_file_a_bug_report
    By submitting a bug report you are helping with the improvement of Fedora and are helping other Fedora users.

    By the way, here is a website that claims to have solved the "error spam": https://h30434.www3.hp.com/t5/Notebo...d/td-p/5933687
    I can't guarantee that it will solve your problem, but it is probably worth a look.

    Hi Donatom,

    thank you for your reply. I'm saving that link for bug reporting, even if as now the problem seems to be frozen. I only see one of those error messages at startup, nothing else. Maybe the latest kernel already brought the necessary changes.

    Should I face it again, at least I know what to do!
