    Can you make a readable photo of the screen with a digital camera and
    post it somewhere?

    Or, connect the box to a serial or a firewire console?

    If the oops is still whizzing by too fast, try enabling
    CONFIG_BOOT_PRINTK_DELAY, see the help text with this option in the
    configurator too, for more info.
