I have to admit I'm seeing absolutely nothing sensible in there.

Call it bad, and see if bisection ends up slowly -oh so slowly -
pointing to some direction. Because I don't think it's the hardware,
considering that apparently 3.16 is solid. And the spews themselves
are so incomprehensible that I'm not seeing any pattern what-so-ever.
