Yes, I agree with you.

My proposal is to keep the effect of my patch as small as possible. For I  
have not validated other platforms, so I can not disable it this way. I  
will try it as soon as possible, if it did has the same problem on other  
platform, I will fix the patch.

By the way, on arm, mips platform, there is no such problem. I have not  
figured our why it does not occur on the platforms.
