I reconfigured the kernel, and everything worked fine. Except now after a period of time (even Idle time, see below) my system has this error: Fatal trap 12: page fault while in kernel mode mp_lock = 01000003; cpuid = 1; lapic.id = 00000000 fault virtual address = 0x30 fault code = supervisor read, page not present instruction number = 0x8:0xc0205661 stack pointer = 0x10:0xff80fcd0 frame pointer = 0x10:0xff80fcd0 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 = Idle interrupt mask = tty bio <- SMP: XXX trap number = 12 panic: page fault mp_lock = 01000003; cpuid = 1; lapic.id = 00000000 boot() called on cpu#1 Uptime: 36m17s I can see that this is a problem with the SMP config. What I don't know is what to do with it, is it hardware, software. I am not sure. This is the first time I have ever been presented with this. I do prefer maybe a point in the right direction rather than the answer as I learn a lot more reading up on it. I just haven't been able to find anything, especially not knowing what I am looking for. Can anyone point me in the right direction? -- //curt
