I was unable to reproduce this on the s390x porterbox (zelenka).
Start 15: quick_tests/kokkos.debug
15/46 Test #15: quick_tests/kokkos.debug
.................................... Passed 559.48 sec
Start 16: quick_tests/kokkos.release
16/46 Test #16: quick_tests/kokkos.release
.................................. Passed 4.18 sec

100% tests passed, 0 tests failed out of 46
Total Test time (real) = 4344.00 sec
Although 559 sec is pretty close to the default test timeout of 600
sec. Matthias suggested doubling the timeout.
