看红色部分
请高手给看下

经过查找，小弟终于找到了问题dm9000 dm9000.0: WARNING: no IRQ resource flags set.
原因原来是没设中断
回去查看把arch/armmach-s3c2440/mach-smdk2440.c文件中的
[2] = {  
             .start = IRQ_EINT7,   
             .end = IRQ_EINT7,  
             .flags = IORESOURCE_IRQ,  
      }  
修改为
[2] = {
.start = IRQ_EINT7, /* 中断号*/
.end = IRQ_EINT7,
.flags = IORESOURCE_IRQ | IRQF_TRIGGER_RISING
}

好帖啊~~~~~~~~~~~~
