Fatal trap 12



  • Hi,
    I've been using the new 2.0RC for a few days and it's crashed on me a couple of times. The 2nd time I noted down the console output:

    
    fatal trap 12: page fault while in kernel mode
    cpuid = 0; apic id = 00
    fault virtual address = 0xc
    fault code = supervisor read, page not present
    instruction pointer = 0x20:0xc0a64c88
    stack pointer = 0x28:0xc33d6ae4
    frame pointer = 0x28:0xc33d6b00
    code segment = base 0x0, limit 0xfffff, type 0x1b
    = DPL 0, pres 1, def32 1, gran 1
    processor eflags = interrupt enabled, resume, IOPL = 0
    current process = 12 (irq19: sis0)
    [thread]
    Stopped at m_copydata+0x38: movl 0xc(%esi),%eax[/thread]
    


  • Can you please share what kind of nics and hardware you have?
    Under what condition this happens?

  • I have many of them, happens on the secondary machine when I am making many changes to the primary machine… I hope this is the problem and that will be solved soon
