I was replicating a filesystem with an application than unmounts
filesystems before sending the snapshots (the unmount is used to check
if the fs is busy before attempting the send).
One filesystem failed to remount and a couple of child filesystems where
sent with their parent unmounted.
On reboot, the parent fs could not mount because the directory wasn't empty.
This appears to have cause the following panic:
