Ok, so I debugged some more, and it looks like I have two separate
problems:

1) Hang when the machine boots "hot". This has been there for long
long time, but the place of hang recently moved, which confused me.

2) next-20171103: I get past kernel boot, but there's kernel panic
(probably) while X is starting. (I can see the capslock led
blinking.). This still happens on next-20171110, if I boot the machine
"cold". This is new.
