Fatal trap 12

Brawndo

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

Hi mdima,

I'm not using CARP. To me, the problem seems to happen randomly….

If someone needs more info, i'm willing to help
