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.
