Interrupt gates are set in linux as set_intr_gate(i, interrupt[i-FIRST_EXTERNAL_VECTOR]); ^ but the 'interrupt' is declared as extern void (*__initconst interrupt[NR_VECTORS-FIRST_EXTERNAL_VECTOR])(void); can anyone possibly tell when are these enteries filled with valid pointers ??? -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
