DVSDK compatibility with 2.6.34 or later kernel (OE or Arago based compilation is preferred) (needed completely tested before november included our applications) can be assured with which kernel version? arago = yes, but it means my all system becomes immediately OLD. kevin's = probably never devel_2_6_35rc2 = when?
