do_populate_sysroot_setscene fails for kernel-module-vspm.bb

WARNING: Setscene task (../meta-renesas-rcar-gen3/meta-rcar-gen3/recipes-kernel/kernel-module-vspm/kernel-module-vspm.bb:do_populate_sysroot_setscene) failed with exit code '1' - real task will be run instead

harunobu.kurokawa , sdesneux  any idea how to fix this ?

The effect is that we will rebuild the kernel every time to extract the sources instead of using the sstate-cache for the modules.
