Current CMA size of 64 Mbytes is right on the edge of being too small for some display managers. With the proposed s5p_mfc patch series that pre-allocate buffers, when display manager starts, it fails to get GEM buffers. Increasing the CMA size to 96 solves the problem.
Change CONFIG_CMA_SIZE_MBYTES to 96 in exynos_defconfig to address the problem.
