Anyone has a idea on this issue?

Did it ever work? If so which kernel version?

It works for 3.15, but failed with linux version 3.16.0-rc1-next-20140617

What about 3.16-rc1 ?

3.16-rc1 still not work. the same issue.

The config file can be simply get from /boot/configxxx. and "make
menuconfig" and save without change anything(default).

Sure, but I don't have access to your box so please ..

   * OS address 9.3.110.192 root/linux123
   * Minicom server: 9.3.191.26 root/linux123
       o minicom -D /dev/ttyS0

          fsp: http://cena-fsp.austin.ibm.com

Please change that password immediately, and don't EVER post the login details
for a machine on a public list again.

Also I'm not offering to logon to your machine and debug it, I'm giving you
advice on how you can debug it.

...OK, got it, my mistake...

Thanks
Mike
