This would suggest that the problem is not with cryptsetup at least. 
Something seems wonky with device-mapper in general.

I've updated the testing machine I was using so that it has the same 
package versions as your machine and it still works for me.

Just to make sure, do you think you could install the Debian packaged 
kernel, boot it and try to setup the mapping with that kernel? (but do 
the things mentioned below first)

If it tries to setup 253:2, that suggests that there are two other 
device-mapper devices already setup...what is the output of "ls -al 
/dev/mapper", "dmsetup table" and "cat /proc/mounts"? Also, are you 
using udev?
