    The "Ugh" is logging the fact someone attempted to handle a page fault while
    having interrupts disabled. This is an extremely bad thing. There are two causes

    1. Incorrect kernel code (I think most of these are now dead)
    2. Some user process as root which has the misguided idea it can disable
    interrupts after using the iopl() syscall. Well it can't. Not unless
    its prepaged everything it needs and mlock()'d those pages

    so its either a kernel or an X bug.
