[求助内核编译问题]make install出现问题

sunday98

我是按照论坛里的帖子做的，2.4.22-->2.6.5,
可是到最后make install出问题了，

[root@daojun linux-2.6.5]# make install
make[1]: >>arch/i386/kernel/asm-offsets.s<< ist bereits aktualisiert.
  CHK     include/linux/compile.h
Kernel: arch/i386/boot/bzImage is ready
sh /usr/src/linux-2.6.5/arch/i386/boot/install.sh 2.6.5 arch/i386/boot/bzImage System.map ""
WARNING: /lib/modules/2.6.5/kernel/drivers/video/neofb.ko needs unknown symbol tosh_smm
/dev/mapper/control: open failed: No such file or directory
Is device-mapper driver missing from kernel?
Command failed

请问是怎么回事啊？
