rmmod: can't change directory to '/lib/modules': No such file or directory
insmod后做rmmod报以下错误：
/tmp/nfs/frank/drv/myled # rmmod led_drv.ko
rmmod: can't change directory to '/lib/modules': No such file or directory
原因是rootfs在/lib下缺乏对应的目录，建立
mkdir /lib/modules
再执行rmmod提示
/tmp/nfs/frank/drv/myled # rmmod led_drv.ko
rmmod: can't change directory to '2.6.35.3-571-gcca29a0-g6335376': No such file or directory
再建立2.6.35.3-571-gcca29a0-g6335376即可解决问题
mkdir /lib/modules/2.6.35.3-571-gcca29a0-g6335376
