petsc-3.22 should work with nvfortran.

Fortran interface in petsc is being over-hauled (in 3.23, and future 3.24 releases) requiring F2008 (and F2023?) features - that some of the older compilers don't support.

[and older petsc releases might have other issues - say using latest cuda version, cmake version etc...]
