Because of missing i2c? Lamobo R1 is listed here:
  https://bugs.debian.org/864536#15

(Didn't check the recursive list of dependencies though.)

If I understood the original submitter correctly, the problem
also exists in the installed system, not only in d-i.  The
i2c-modules udeb issue (or other modules unavailable in the udebs
but available in the regular kernel deb) would explain problems
inside d-i, but not in the installed system.

Heinrich, can you clarify on that?

Yes, the problems exists both in the installer and in an installed system.

I set up the installed system via debootstrap:
