I am a bit confused now, since you said removal of this solves your 
issue. Now the removal of which you say that causes problems. The 
original post had nothing to do with this case, as that user did not 
have that change in the code.

So a bit of testing with the various options such as what causes your 
problem from a cold bott can help to identify this problem, rather than 
a reset or a module load, which i explained earlier.
