deleting a btrfs subvolume shut up a server

[Toralf FÃrster]

I created at a 3 TB btrfs formatted disk a btrfs subvolume, unpacked a minimal Gentoo Linux in it, created in addition few files within it under ./tmp and bind mount from the host few files onto those files. If I now delete in another terminal the subvolume - then the server dies immediately

It is a headless server, I had to request a manually reset to get it back.
Nothing in the syslog (syslog-ng 3.6.2) - the server was just shot in he head.

This happened 2 times in a row. Host is a stable hardened Gentoo with 4.0.2 kernel.
