Because of the speed of development, you should run the latest kernel you can (either the latest release kernel from kernel.org, or the latest -rc kernel. Kernel 3.8 is OLD for btrfs testing and the 3.x.y stable releases don't pick up all the fixes. You're running a filesystem still marked experimental and under HEAVY development, and at two versions behind current 3.10 release (with 3.11-rc1 now out, altho I can understand being cautious enough not to want to run that early an rc), you are behind indeed, and missing critical btrfs fixes that have been applied in the last two kernel releases. Here, I try to switch to a new kernel series (I run Linus mainstream git) about rc2 or so, by rc3 at the latest so there's time to resolve any new kernel problems I find and report, but even for the more conservative btrfs testers (who by definition are reasonably leading/bleeding edge or they'd not be running an experimental filesystem), rc4 or 5 should be quite stable and I'd recommend running it, unless there's a specific reported regression that affects you so you can't, and you're waiting on a fix. In particular, I believe there's several fixes for just that sort of bug in 4.10, altho I'm not technical enough to parse the stack-trace and be sure about your specific issue, but I'd definitely recommend trying it. If you're still seeing the issue with 4.10, or with the latest 4.11 series git checkout if you're brave enough to try it at the rc1 stage, /then/ it's time to report it here. =:^) -- Duncan - List replies preferred.
