Fatal trap 12: page fault while in kernel mode

  • Hello.

    We are having multiple random crash with pfsense on netgate sg5100.
    We are getting this issue: Fatal trap 12: page fault while in kernel mode.
    Please see the attached dump log file.
    We suspected hyper-threading but the CPU doesn't have hyperthreading.
    No PHP were errors found.

    Thanks for any help.

  • Log file?

  • Netgate Administrator

    Yes, we would need the full crash report. And multiple crash reports for comparison is useful.

    Open a ticket with us if you think it's a hardware fault or don't want to post the crash reports publicly.


  • Maybe next time put all these logs in one zip file so that people trying to help you don't have to manually download many things?

    The key error is fault code = supervisor read data, page not present, which leads me to believe potentially it's a memory error of some sort. Crashes like that are usually hardware-related.

  • Also @stephenw10
    I would like also to know if it normal that we cannot netgate coreboot upgrade even if we have bought a sg5100


  • Netgate Administrator

    Yes, that's expected. The SG-5100 does not run Coreboot.

    @kom lazy 😂
    pid 12 "irq292: ix0:q1"
    ix0 is the network card
    pid 12 "irq297: ix1:q1"
    ix1 is the network card

    this are repeated on your dump.
    open a ticket as suggested by @stephenw10

  • Netgate Administrator

    Yes, please open a ticket. I would like to look at your config for this.

    The crashes are all almost identical which indicates a software issue. And they are on all interfaces including both igb and ix which is very unusual.
