Even I am facing the same issue, but seen only few instances of failures. Not able to concretely figure out exact steps to replicate the issue. Is it better to remove the addtask shared_workdir_setscene ? If you see do_deploy task in kernel.bbclass, it doesn't handle the setscene task either Thanks, Manju -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
