Thanks, no worries! I got myself confused too. :)

The config you sent looks like I'd expect now too. Questions for you, if
you have time to diagnose further:

- Are you able to catch the very beginning of the crash, where the Oops
  starts?

- Does pstore work for you to catch the crash?

- Can you try booting with this patch applied?

I'll try to see if I can figure out anything more from the images you
posted.
