References: <543D555B.50708@pobox.com> In-Reply-To: <543D555B.50708@pobox.com> Content-Type: text/plain; charset=utf-8; format=flowed Sender: linux-btrfs-owner@vger.kernel.org List-ID: I didn't notice a corruption on other filesystems with kernel 3.17.0. Also I didn't experience any hangs except when trying to mount a corrupted btrfs but this was causing a hang within less than 10 seconds. It could be that your problem is unrelated and that the corruption you are experiencing is due to an unrelated hang followed by a hard powerdown. Have you been able to capture any btrfs related kernel panics ?
