无线网卡一ifconfig up，内核就崩溃

zhlyp

处理器：S3C2410
系统：LINUX 2.6.14
无线网卡：ASUS WL-167g

下载的是RT73_Linux_STA_Drv1.0.4.0.tar.gz
按照《TL-WN321G (rt73)USB无线网卡驱动在armlinux平台上的移植》更改了makefile

在开发板上insmod rt73.ko

插上无线网卡，正常，能读出idVendor和idProduct
iwconfig也能发现无线网卡rausb0

只是用ifconfig rausb0 up,就会出现系统崩溃信息

求救啊 ，怎么解决？

可以肯定的说，是无线网卡的驱动出了问题。可以看看网卡驱动实现的read，write函数。

我感觉这像无线网卡中断冲突

yuanyang317

你好，请问你这个kernel的问题解决了吗？我现在也是在移植这个网卡，也是这样，一ifconfig rausb0 up系统就panic了，请问是怎么回事啊？
