標(biāo)題: 無線網(wǎng)卡一ifconfig up，內(nèi)核就崩潰
處理器：S3C2410
系統(tǒng)：LINUX 2.6.14
無線網(wǎng)卡：ASUS WL-167g

下載的是RT73_Linux_STA_Drv1.0.4.0.tar.gz
按照《TL-WN321G (rt73)USB無線網(wǎng)卡驅(qū)動在armlinux平臺上的移植》更改了makefile

在開發(fā)板上insmod rt73.ko

插上無線網(wǎng)卡，正常，能讀出idVendor和idProduct
iwconfig也能發(fā)現(xiàn)無線網(wǎng)卡rausb0

只是用ifconfig rausb0 up,就會出現(xiàn)系統(tǒng)崩潰信息

求救啊 ，怎么解決？

可以肯定的說，是無線網(wǎng)卡的驅(qū)動出了問題�？梢钥纯淳W(wǎng)卡驅(qū)動實(shí)現(xiàn)的read，write函數(shù)。

我感覺這像無線網(wǎng)卡中斷沖突

你好，請問你這個kernel的問題解決了嗎？我現(xiàn)在也是在移植這個網(wǎng)卡，也是這樣，一ifconfig rausb0 up系統(tǒng)就panic了，請問是怎么回事��？
