How to recover from such task hung status? Hi David, a simple btrfs user reply here. I don't know if this will solve your issue at hand, but when using btrfs it is strongly advised to run a much more recent kernel than 3.2 as found in Ubuntu precise (12.4). The reason is that they were plenty of bug fixes related to btrfs that you would miss by sticking to an old kernel. Could you please try the latest 3.11 (or 3.10) kernel available? If this doesn't fix your issue, please report back so that we can investigate further.
