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: https://www.moparisthebest.com/btrfs/archnetconsole.txt I was also able to mount it ro so I ran the grep you asked for: https://www.moparisthebest.com/btrfs/enospcdebug.txt 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!
