When copying large files dm-crypted machines (swap+root) are often not very usable. Also in some cases I see no i/o happening in vmstat, sometimes for a minute, while lots of processes are blocked waiting for data read and decrypted from disk. But I don't have a recipe for reproducing this so far and only tested up to 2.6.21.*.
