Next boot results in hang. It boots ok twice in between. v4.10-rc6: ok ?! 34e00accf612bc5448ae709245c2b408edf39f46 : ok? v4.10-rc6-feb3: ok?! (with config.ok, and with original config. Hmm?) This machine was pretty reliable (except rowhammer), but I admit their EC code may leave something to be desired. Sometimes it runs without power LED lit (usually after strange crashes), sometimes _two_ long presses are neccessary to power it off. So... yesterday it hung on cold boot, but not on reboot. Verified 5 times or more. Today, I can't reproduce the hang. Strange :-(.
