The blend test uses the userptr functionality of exynos-drm, which is currently not safe to use. If the kernel hasn't been build with exynos-iommu support, then the blend test is going to produce (kernel) memory corruption, eventually leading to a system crash. Disable the test for now, until the kernel code has been sanitized.
