Anyone who typically updates on nightly kernels I would recommend freezing and not updating until we clear up some issues gifted us by some large amount of upstream changes that broke well, pretty much everything.  I will update this thread as things get brought back to life.   June 7th 2018:  I've made a branch (rockchip-default) to work out the kinks.  So far I have the board booting and Mali working again (with an initial error on load) , however there is no HDMI terminal,
