Abstract
This continues recent work in an article by Corner et al. (2004). A particular question was left open: Is it possible to carry over the results concerning the undecidability of torsion-free Crawley groups to modules over the ring of p -adic integers? We will confirm this and also strengthen one of the results in Corner et al. (2004) by replacing the hypothesis of ◇ by CH . For details see the introduction.
