Runner coyote10 is unstable.

The CUDA device may become hidden at random in the middle of the testsuite:

103/184 Test  #10: test_checkpoint__therm_lb__p3m_gpu__lj__lb_gpu_binary .........***Failed    1.70 sec
ERROR: CUDA error: no CUDA-capable device is detected
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMMUNICATOR 3
with errorcode 1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------

Or before the testsuite starts:

In both cases the GPU was detected at the beginning:
