But we are neither perfect nor can we predict every 10e12 possibilities to produce a hidden bug. I cannot reproduce it here. That's why I asked for a bainary Image of the flash content, but I received none until now. We can only solve problems, which are either reproducable or which can be reproduced by some user supplied pattern / image. We all do our very best to make this code stable and reliable, but we need the help from _USERS_ to detect insufficiencies. That's the way open source software works. If we don't get the requested feedback / help we can only say: You got the code. Feel free to fix it. -- Thomas ________________________________________________________________________ linutronix - competence in embedded & realtime linux http://www.linutronix.de mail: tglx@linutronix.de
