the kernel did because you don't return the proper value for "I handled the IRQ" from your ISR.
Also I don't see where you call cleanup_module(), the function that does the deregistration of the chardev... where do you call that ???? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
