AM3358 内核3.2，有什么好用的USB WiFi网卡没有，帮忙推荐几个
使用RT8188和RT5370都会发生内核挂掉的错误，怎么解决？
RT5370的2个错误，记下来了，8188的没记录
RT5370使用的驱动是DPO_RT5572_LinuxSTA_2.6.1.3_20121022.tar.bz2，编译器是gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux
开机后，加载驱动连接上无线路由器，ping www.baidu.com，刚开始正常的，过40,50分钟左右就会发生内核错误
错误1，如下
Unable to handle kernel paging request at virtual address 0008cb4b
pgd = c0004000
[0008cb4b] *pgd=00000000
