With z/VM 5.2 the Diag250 does support 64 bit. Because earlier VM releases did not, I think at some point the Linux diag driver was made to refuse working in a >2G virtual machine at all. The simplest check would be to define the guest <2G and see if that solves you problem. Note that the dasd_diag_mod only wants to work with disks that have been prepared with the CMS RESERVE command. You might want to look at the SWAPGEN program to do that before you start Linux.
