request_irq takes a virtual IRQ number, not a hardware IRQ number. You need to get the virtual IRQ number from irq_of_parse_and_map(), or from irq_create_mapping(). This would probably confuse far fewer people if we used pointers in the API rather than virtual IRQ numbers... -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
