    The CIA FLAG interrupt executes amiga_interrupt() which then calls
    parport_generic_irq().

    The call to parport_generic_irq() can be commented out and the printer
    still prints exactly the same as with the call, dropping about every 2nd
    char.

    The interrupt is not doing anything, parport_ieee1284_write_compat() is
    sending out bytes irrspective of interrupts.

    Ken.
