Tty Pointer.  Tty data structures are allocated at open time, so they
can't be used if an interrupt occurs before open.  It is supposed to
be impossible for interrupts to occur before open, but it happened
before for another reason.

Try to use IRQ7 for something unimportant like lpt or something that
won't mind the extra interrupts (like lpt again).
