Hiya, I got below those last night. That was 3 minutes after a
bunch of rsync and ntfsclone processes started.

It's the first time it happens. I upgraded from 3.0rc6 to 3.0
yesterday.

Ok I fixed that recently and Chris just sent it to Linus.  The patch you are
looking for is

Btrfs: use a worker thread to do caching

[...]

Thanks a lot Josef,

That seems to have done the trick. I've not reproduced the issue
yet with that patch applied. Strange that I only get the issue
with 3.0 and not 3.0rc6  though....
