initrd-xxx.img create dracut not correct

[yeyouqun <yeyouqun1981-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Recently I upgraded linux kernel to 3.6.10 and upgrade dracut version to 
024, system starts up OK on 3.6.10. But when I upgraded kernel from 
3.6.10 to 3.8.2, dracut failed to start up the system. Message when 
start up reads:

......
    dracut: dracut-dracut-024-
     rpcbind: cannot create socket for udp6
     rpcbind: cannot create socket for tcp6
     mount: unknoun filesys
     udev: starting version 147
     systend-udevd (139): /proc/139/oom_adj is deprecated, please use
     /proc/139/oom_score_adj instead.
     dracut Warning: Could not boot.
     dracut Warning: Could not boot.
     Dropping to debug shell.
     /bin/sh: can't access tty; job control turned off
......

But when I unpack the initrd-3.8.2.img, the /lib/modules directory shows 
as below:

modules ---- 3.8.2
          |
          |__ 3.6.10

all the kernel modules reside in "3.6.10" directory and other files, 
such as "modules.dep" and etc. reside in 3.8.2, I think this is the 
reason why system can't start up.

I upgraded kernel by the steps as(in kernel source tree of 3.8.2):

     make
     make modules_install
     make install

Any one can tell how to fix this behavior of dracut?
