See routine "PW/potinit.f90". Assuming that the file is really there with the expected name, the only possible reason is that process 0 of the second run (when the file is read) does not see the *.save directory, because it is executed on a different processor with respect to the first run (when the file was written). It is a known problem if you use local filesystems and there is little one can do, other than copying the needed files to a place where they can be found. Paolo
