I just tried to reproduce this issue, it seems to work for me on
Debian/wheezy as well as on Debian/jessie (as of today with
linux-image-3.12-1-amd64 v3.12.9-1 and kpartx
0.4.9+git0.9c3c5172-1). [I just didn't use your custom config and
package list and used amd64 instead, but I used the command line
from your script, ftr.]

Maybe check whether the updates included in the current linux kernel
package 3.12.9-1 fixes the issue for you?
