请教一个在linux2.4下驱动S3C44B0上的网络和液晶显示屏驱动问题
我把我编好的内核移植到 S3C44B0 上时，上电启动后如下：

可是在 ping 或者是在 ifconfig eth0 192.168.0.28 的时候没不能通过啊 ！
我的液晶显示好象也有了，可是就是在虚拟目录下看不到，这是怎么一回事情！希望高手指点！谢谢！QQ：99592177！
说明：在ping 127.0.0.1的时候能 通过的！
[解决办法]
那可是加载有问题吧
你的驱动是动态加载的??
module
[解决办法]
其实一提到软硬的问题,就让人头大,主要原因
软件可能受到硬件的影响,或者相反等等.
你这种问题,如果内核编译没有问题,或许可能是硬件.但不排除其它因素.
如果不行,你可以试着,再编译几次内核,选上一定要选上的.试几下.
有可能你的加载模块有些没有弄上.
想的.
[解决办法]
先看看eth0 的状态 cat /proc/net/dev
lspci
cat /proc/interrupts
确定驱动和内核都没有问题，仔细检查一下的内核参数。
ping不通不能代表你的网卡不能工作，如果ping是时断时好的，考虑网络线路本身问题、网卡器件稳定问题、内核调度是否繁忙，网络是否繁忙等原因
