Hello,
I have installed 4.8-stable on my dual processor HP system. 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?
