Hi,

On stable v4.14.40-rc1, commit below breaks kernel boot on ARMv7 board (Odroid XU3 with Samsung Exynos5422, exynos_defconfig). The kernel hangs on "Starting kernel ...". Full log: http://www.krzk.eu/#/builders/1/builds/1897

The board boots from TFTP with NFS root (NFSv4).

Thanks for this info, I've now dropped this patch from 4.14.y and 4.16.y.
