OK, after a week of further testing I don't think the issue is resolved.
I am moving about 150GB of data around and the system gives hard locks.
Nothing in the syslog, however I had a top running at failure and the
BTRFS processes went through the roof:
0 0 0 R 100.0 0.0 0:51.50 [btrfs-transacti]
0 0 0 R 72.1 0.0 0:11.68 [btrfs-flush_del]
0 0 0 S 72.1 0.0 0:17.36 [btrfs-flush_del]
0 0 0 R 57.8 0.0 0:12.34 [btrfs-flush_del]
0 0 0 S 57.5 0.0 0:14.28 [btrfs-flush_del]
I will remove tag
