Comment 1 Andrew McNabb 2013-01-25 18:12:14 UTC

This kernel bug occurred after physically removing a faulty disk that was part of a btrfs filesystem.

Comment 2 Josef Bacik 2013-09-23 20:43:22 UTC

If you can reproduce on a recent kernel please file a bug at bugzilla.kernel.org and set the component to btrfs.
