Sadly it causes a regression on one of my test systems (ARM 32bit, Samsung Exynos5422 SoC based Odroid XU3 board with eMMC). The system boots fine and then after a few seconds every executed command hangs. No panic/ops/any other message. I will try to provide more information asap I find something to share. Simple reverting it in linux-next is not possible due to dependencies. Best regards -- Marek Szyprowski, PhD Samsung R&D Institute Poland
