I just booted my backup box with 4.8rc8 and started an rsync onto
btrfs and it panic'd with OOM a couple hours later. I thought the OOM
problems from 4.7 we're supposed to be fixed in 4.8, or did I get that
wrong? No users or anything else on the system.

Keep in mind that those problems are generic, other filesystems also
suffer: http://www.spinics.net/lists/linux-mm/msg114123.html
I don't see any recent compaction-related patches in Linus' tree at
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/mm/
..so it seems they have not been merged yet.
So unless they get merged in the last minute it looks like 4.8 will
be DOA.

Sorry, that was not quite correct. -stable 4.7.x and 4.8 contain
a workaround (http://goo.gl/DiwfPH) that is supposed to help.
That went into 4.8rc8 already, so not sure what happened in your case.
