Ok, what kind of ass-hat idiotic thing is this? irqreturn_t uio_irq_handler(int irq, void *dev_id) { return IRQ_HANDLED; } exactly what is the point here? No way will I pull this kind of crap. You just seem to have guaranteed a dead machine if the irq is level-triggered, since it will keep on happening forever. Please remove. YOU CANNOT DO IRQ'S BY LETTING USER SPACE SORT IT OUT! It's really that easy. The irq handler has to be _entirely_ in kernel space. No user-space ass-hattery here. And I don't care one whit if it happens to work on parport with an old legacy ISA interrupt that is edge-triggered. That's not even the interesting case. Never will be. NAK NAK NAK NAK.
