Hmm...do you know how to build debian packages from source?

It would be great if you could download the devmapper source package 
("apt-get source libdevmapper1.02"), edit the file 
devmapper-1.02.12/lib/ioctl/libdm-iface.c and add the line:

"fwrite(dmi, dmi->data_size, 1, stderr);"

at line 1553 (just before the "log_debug" statement).

Then build it ("dpkg-buildpackage -us -uc -rfakeroot"), install the 
generated debs and try to run dmsetup again (without the -v flags). 

Capture stderr to a file and mail it to me (it will contain the 
passphrase you used, but for this test that would just be the dummy pass 
from the map file).

The command to execute would be:
"dmsetup create root map 2> /tmp/dmsetup.stderr"
