You should avoid using max_part=, which changes the way minors are
assigned. It's not compatible with SUSE's pre-created devices nodes.

losetup has proper loop allocation code, pre-creation is not needed.

Also loop devices have proper native partition support in the kernel
since quite a while, and this (broken) option should just not be used
today.
