内核编译问题？

杨志全

编译Linux-2.6.0-test9不成功，我的编译过程如下：
1.make mrproper
2.make menuconfig
3.make bzImage
4.make modules
5.make modules_install
6.make
make [1] `arch/i386/kernel/asm-offsets.s`is up to date
  CHK include/linux/anpile.h
  kernel : arch/i386/boot/bzImage is ready
  Building moules stage2
  Moupost
7.make install
make [1] :`arch/i386/kernel/asm -offeset.s`is up to date
  CHK include/linux/comapile.h
  Kernel : arch/i386/boot/bzImage is ready
  sh  /usr/src/linux-2.6.0-test9/arch/i386/boot/install.sh  2.6.0-test9 arch/i386/boot/bzImage system.map"
All of your loopback devices are inuse
make [1]***[install]  Error1
make *** [install]Error2
请教loopback devices是什么？我的编译过程出了什么问题？如何解决？
