I have picked the additional patches to my tree, which currently has a bunch of other stuff in it, in particular v4 of the IOMMU series. Anyway, now the 'modetest' application immediately crashes the system, but I get a least something on the serial console: http://www.math.uni-bielefeld.de/~tjakobi/archive/odroid_modetest_crash_sysmmu.txt So this is probably due to the IOMMU. Please note that DRM IOMMU support (CONFIG_DRM_EXYNOS_IOMMU) was disabled (!) in my config. CONFIG_EXYNOS_IOMMU however was on. I'm going to retest with the IOMMU series removed and CONFIG_EXYNOS_IOMMU disabled as well. Just posting this already since you're probably interested in these 'side-issues' as well.
