Ok (i was though expecting a better result)
Some questions:

* Does reverting changeset 5887 make any difference for you ? 
* Does changing SearchRange (in stb0899_drv.c) up and down 
   change situations for you (better/worser) ?

I have some thoughts, but to get the clarification the relevant 
person will be back after the 29th this month only. But that 
shouldn't be a show stopper for the tests.

Will think of possibilities of other issues as well. All you guys are 
having similar results ? Or should i wait for some more test results
before starting to pull out hair again ?
