    Using the debug option in the boot menu gives (hand transcript):

    ----------
    Fatal trap 12: page fault while in kernel mode
    fault virual address = 0x0
    fault code = supervisor read, page not present
    instruction pointer = 0x8:0xc057c368
    stack pointer = 0x10:0xdc5a8b58
    frame pointer = 0x10:0xdc5a8b58
    code segment = base 0x0, limit 0xffffff, type 0x1b
                          = DPL 0, pres 1, def32 1, gran 1
    processor eflags = interrupt enabled, resume, IOPL=0
    current process = 227 (devd)
    trap number = 12
    panic: page fault
    ----------

    Being a physicist, I naturally repeated the process a few times and got the following lines different:

    ----------
    stack pointer = 0x10:0xdc5b4b58
    frame pointer = 0x10:0xdc5b4b58
    current process = 245 (devd)
    ----------
    stack pointer = 0x10:0xcc50eb58
    frame pointer = 0x10:0xcc50eb58
    current process = 245 (devd)
    ----------
    stack pointer = 0x10:0xdc5b4b58
    frame pointer = 0x10:0xdc5b4b58
    current process = 245 (devd)
    ----------
    stack pointer = 0x10:0xdc5b4b58
    frame pointer = 0x10:0xdc5b4b58
    current process = 245 (devd)
    ----------

    ... don't know if that helps.
