I managed to get more output from arch/4.7.2 using netconsole, I did end
up with duplicate lines somehow though which uniq fixed, but some of the
crash is mixed together on the same line, I didn't mess with that for
fear of taking out something important:

I was also able to mount it ro so I ran the grep you asked for:

I tried mounting with mount -o rw,skip_balance and it still locked up,
so for now it's read-only...

Let me know what else I can provide or try.  I haven't been able to boot
with a 4.7 kernel on my ubuntu install so I figure 4.8 will be the same,
I guess I'll need to permanently install something like arch to a flash
drive and try 4.8 from there.

Thanks!
