小弟写了个camera驱动，用到了中断，具体如下：
在/include/asm/arch-s3c2410/irqs.h 中有定义
#define S3C2410_CPUIRQ_OFFSET  (16)
#define S3C2410_IRQ(x) ((x) + S3C2410_CPUIRQ_OFFSET)
#define IRQ_S3C2440_CAM_P S3C2410_IRQ(66)  
于是我就这样申请中断：
request_irq(82,Cam_Isr,SA_INTERRUPT,"DEMO",NULL);   //camera_p的中断号码
但是运行应运程序时候出现如下错误：

已经困了好久了，请大家帮忙看看！急！！！

什么版本的内核？ 2.4？
