我在FC6 下编译2.6.23 的代码（采用默认选项），编译过程：
make menuconfig
make bzImage
make modules
make modules_install
make install
然后重启选2.6.23内核，出现如下错误：
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!

请高手赐教，非常感谢。　　　　　　

你还需要mkinitrd  initrd-2.6.23.img 2.6.23,然后把生成img文件拷到 /boot下面。
