I'm not have much experience with linux kernel architecture, so I don't 
know where I can focus on.

Currently, I'm suspecting these module are affected with this Oops: 
Block I/O management and filesystem, some Wait Queue  ? Is that correct ?
Or would you give me some suggestion what is the most suspicious ? or 
some debugging option you told above ?

Thanks for your help,
