Fatal trap 12 when enabling wifi.



  • Hi.
    Sometimes immediately, sometimes after a few minutes when I have enabled my wifi the system crashes. In this example, the machine has been running for over a week, then I enable wifi and boom.

    Running:
    2.0-RELEASE (i386)
    built on Tue Sep 13 18:02:53 EDT 2011 on a http://www.fit-pc.com/web/fit-pc2/fit-pc2i-specifications/

    Error:
    Fatal trap 12: page fault while in kernel mode
    cpuid = 1; apic id = 01
    fault virtual address  = 0xc5e6c908
    fault code              = supervisor read, page not present

    panic: page fault
    cpuid = 1
    Uptime: 9d20h48m31s
    Cannot dump. Device not defined or unavailable.

    The wlan chip is:
    run0: MAC/BBP RT3070 (rev 0x0201), RF RT3020 (MIMO 1T1R)
    run0: firmware RT2870 loaded

    I have seen this thread, same computer with the same trap number error:
    http://forum.pfsense.org/index.php/topic,38708.msg199529.html#msg199529

    Is there any known problems with this wifi-chip?

    How do I save coredumps when booting out of a usb-stick on a nanobsd-kernel? Can I mount another usb-stick and enable a core output on that device so I can backtrace the error?



  • Have you configured the WiFi interface as AP?

    Yep.
