With watching a movie I noticed this:

At the time I still was configuring the plug-ins
for the media player; so maybe this was the
initial cause. In any case better to report
than not at all.
 ohh and another thing, I owe a thanks to
all of you guys working hard on these kernels,
I finally have a tainted free system : )
regards;
