Hi, We are getting boot-time system hang on Exynos4210-based Origen board if the kernel (right now testing v3.13-rc6) is built using exynos_defconfig, disabling SMP support and enabling CPU_IDLE support. The boot log can be found here[1]. Git bisect points to following commit. commit 87107d89052bcec1fe91b309631de4ed294a5171 Author: Arnd Bergmann <arnd@xxxxxxxx> Date: Wed Jun 19 01:36:52 2013 +0900 ARM: EXYNOS: Remove legacy L2X0 initialization Since Exynos is now supporting only DT-based boot, the old L2X0 initialization code is not needed anymore, so exynos4_l2x0_cache_init() can be greatly simplified.

Any idea what else we might be missing?
