Also try yffs2 on USB. It's more likely a filesystem issue (rather than block layer), probably because e.g. lack of splice() implementation on your other filesystems. I remember having to add splice() support to NFS around these kernel versions, so I would not be surprised if other filesystems also did lack splice support. Also try running lttd in verbose mode to see if splice fails.
