I just rebooted a VM into a 4.7 kernel. The joy didn't last long. After 177 seconds the btrfs data partition (root is on ext4) locked up. Worse, it keeps locking up on any action performed even when rebooting it with older kernels again. D: The filesystem initially mounts fine, but then locks up again immediately. Linux stacheldraht 4.7.0-rc4-amd64 #1 SMP Debian 4.7~rc4-1~exp1 (2016-06-20) x86_64 GNU/Linux ps output shows [btrfs-transaction] in D state: root 1108 0.0 0.0 0 0 ?

I force-rebooted the poor thing again, and mounted the filesystem ro. It mounts without any complaint. I can see all files now, I can do sub list etc...
So I think I'm going to copy some data to a new filesystem on a new block device just in case. The thing has to move to new storage anyway it's about 100 subvolumes with about 150GB of data, so that's a nice excercise with send/receive.
