Now the question is: Is something changed outside of the skbuf (maybe in udp.{c,h}?) or is it because the dts uses a different approach of talking to the MAC of the lpc3250? > > I may try a more recent kernel with a dts file (maybe a 4.x.x one), but I think that will be impossible to backport a patch for our 2.6 kernel :( > > If anybody has any more ideas about why the dts kernel does not panic, you're very welcome. > > Mit freundlichen Grüßen / With kind regards > > Marcel Hellwig > B.
