I have done as requested, but I still think this bug covers it.  Basically it
amounts to "Broken Carrizo+Topaz [on HP?] power management issues lead to black
or flickering screen with amdgpu".  Since my latest working solution (boot into
X w/ power management enabled, then reboot with it disabled) does not involve
playing with the crtc switch, I am even more convinced of this.  The only part
that isn't covered is the system hang when killing X with crtc 1 enabled, but
that's not something I ever cared about, anyway.
