I currently have a btrfs partition that, when mounted, ends up
freezing my system. The only error I get when running btrfs check on
it is a whole lot of "bad extent ... type mismatch with chunk"
I've added the patch https://patchwork.kernel.org/patch/7687611/ on
top of btrfs-progs v4.3.1 (
7c3394ed9ef2063a7256d4bc078a485b6f826bc5), with no change.
dmesg reports first the following message twice

Seems to be a bug related to delayed refs and scrub.
Although your 4.1 is unaffected by the delayed ref regression introduced
in 4.2, but I'm afraid there may be some fix in recent kernels related
to scrub/delayed ref.
Would you please try 4.4-rc kernel and see if it still triggers the bug?
And, it would be much better if you can provide some info about the
operations you are doing when the bug is triggered.
This should help us to reproduce the bug.
Thanks,
Qu
