FYI...

Various new exynos5 boot failures starting next-20141117. Looking in the boot logs, the boot stops during DRM initialization.

Note that the boot failures are only on exynos_defconfig, and not multi_v7_defconfig.

As might have been expected, reverting the change that enables the DRM/display options in exynos_defconfig fixes the problem.

[1] commit 0ef76aea7a344ac520b02822a8080797fa06124c Author: Javier Martinez Canillas javier.martinez@collabora.co.uk Date: Thu Nov 13 11:51:42 2014 +0900

ARM: exynos_defconfig: Enable options for display panel support

Many Exynos devices have a display panel. Most of them just have a simple panel while others have more complex configurations that requires an embedded DisplayPort (eDP) to LVDS bridges.

This patch enables the following features to be built in the kernel image to support both setups:

- Direct Rendering Manager (DRM) - DRM bridge registration and lookup framework - Parade ps8622/ps8625 eDP/LVDS bridge - NXP ptn3460 eDP/LVDS bridge - Exynos Fully Interactive Mobile Display controller (FIMD) - Panel registration and lookup framework - Simple panels - Backlight & LCD device support
