Please provide the basic parameters of the device e.g. dmsetup info -c dmsetup table dmsetup status and then I think we'll probably want to see your metadata (or the relevant part of it) at the point where it hangs. The trace shows it's applying a 'discard' to the metadata and releasing blocks when the problem occurs.
