1. 内核启动过程中CS8900驱动始终没有加载

最终发现跟device注册有关，修改mach_smdk2410.c文件如下：

/* CS8900 */static struct resource s3c_cs89x0_resources[] = {[0] = DEFINE_RES_MEM(0x19000000, SZ_1M),[1] = DEFINE_RES_IRQ(IRQ_EINT9),
};static struct platform_device s3c2410_cs89x0 = {.name		= "cirrus,cs8900",.id		= -1,.num_resources	= ARRAY_SIZE(s3c_cs89x0_resources),.resource	= s3c_cs89x0_resources,
};static struct platform_device *smdk2410_devices[] __initdata = {&s3c_device_ohci,&s3c_device_lcd,&s3c_device_wdt,&s3c_device_i2c0,&s3c_device_iis,&s3c2410_cs89x0,&s3c_device_usbgadget,&s3c_device_usb_hsudc,&s3c_device_sdi,	
};

然后CS8900driver能够正常启动并检测到设备。

2. 当设置eth0时，kernel crash
