This only appears to happen when using exynos_defconfig and boots fine with multi_v7_defconfig. The issue seems to be intermittent, so is not reliably reproducable and difficult to bisect. Here are a few boot logs from recent mainline/linux-next kernels that are failing: mainline/v3.17-rc3-165-g56c2285: http://armv7.com/scheduler/job/5525/log_file#L_59_276 mainline/v3.17-rc3-176-g2b12164: http://armv7.com/scheduler/job/5595/log_file#L_59_278 mainline/v3.17-rc4-131-gd030671: http://armv7.com/scheduler/job/5770/log_file#L_193_277 mainline/v3.17-rc4-146-g619df5d: http://armv7.com/scheduler/job/6014/log_file#L_124_0 next/20140908: http://armv7.com/scheduler/job/5815/log_file#L_59_276 next/20140910: http://armv7.com/scheduler/job/6161/log_file#L_59_278 The ramdisk is used is a very minimal open embedded based filesystem, which can be found here: http://images.armcloud.us/lava/common/linaro-image-minimal-initramfs-genericarmv7a.cpio.gz.u-boot Please let me know if any more information is needed to help reproduce.
