I've never seen this issue, so I may not be the right person to give advice here. But at a glance, it looks like lvm and device-mapper are incompatible or something similar. If I were in your place I would try differrent versions of lvm2, device-mapper and/or kernel.
FYI, my configuration works with kernel 2.6.16-r1, device-mapper 1.02.03 and lvm2 2.02.05.
