user mode linux 出问题

lysddp

(实验环境是64位的ubuntu10.10,编译的是2.6.38的内核)
我是这样子做的：
一、
make ARCH=um defconfig
make ARCH=um menuconfig


然后选择了kernel hacking 中的：
1)complie the kernel with debug info
2)complie the kernel with frame pointers
保存.config

二、
make ARCH=um
make modules_install INSTALL_MOD_PATH=mods ARCH=um

三、
1）到官网下载了64ubuntu10.10的根文件系统,root_fs
2)将root_fs挂载到 /mnt,然后将源码下 /mods/lib/modules/2.6.38全部拷贝到根文件系统/lib/modules下，然后卸载该文件
3) 制作交换分区文件系统swap_fs

四、
1)运行   ./linux ubda=./root_fs  ubdb=./swap_fs con=pts con0=fd:0,fd:1



可是执行的过程下却一直卡在那边。不知道是怎么回事，麻烦大哥大姐指点下，谢谢了。
