    Hello, I am having the following problem. About a week or so ago this
    started. My box running 4.9-STABLE keeps panicing and rebooting, below
    is an output of dmesg -a. Also i have tried to replace the memory and
    the hard drive is only 5 months old or so. I have also cvsup'ed and ran
    make/buildworld and rebuilt my kernel. It doesnt appear to be
    overheating either. Any help would be greatly appreciated, thanks

    Here is the error i recieve

    Fatal trap 12: page fault while in kernel mode
    fault virtual address = 0xa83a0028
    fault code = supervisor read, page not present
    instruction pointer = 0x8:0xc3e4ea17

    current process = Idle
