It turns out that the problem was due to PETSc and not to libMesh. If I build libMesh without PETSc support I have no compatibility issues.
Actually I'm not able to run PETSc examples compiled on the xeon front-end on opteron nodes. I just get "Illegal Instruction" Are there any flags for the compiler to be safer with the architecture type?
