Hi, I run 3.18-rc3 kernel on BeagleBone Black. It doesn't have Exynos DRM of course, but I run multi-platform kernel where CONFIG_DRM_EXYNOS is set to 'y'. The issue here is that the platform probe/init goes to infinite loop as the following: [ 5.717343] platform exynos-drm: Driver exynos-drm requests probe deferral [ 5.726848] exynos-drm-ipp exynos-drm-ipp: drm ipp registered successfully. [ 5.734700] platform exynos-drm: Driver exynos-drm requests probe deferral [ 5.744044] exynos-drm-ipp exynos-drm-ipp: drm ipp registered successfully. [ 5.752010] platform exynos-drm: Driver exynos-drm requests probe deferral [ 5.761377] exynos-drm-ipp exynos-drm-ipp: drm ipp registered successfully. [ 5.769291] platform exynos-drm: Driver exynos-drm requests probe deferral It is quite unexpectable behavior. I would expect that the exynos-drm failed to initialize with 'no device' error.
