Running the ring stress autotest causes the test to hang as follows:

~/src/dpdk/build/app/test/dpdk-test --log-level=3Ddebug -l 2-127 --no-pci
--no-huge ring_stress_autotest
EAL: Detected CPU lcores: 128
EAL: Detected NUMA nodes: 2
EAL: Static memory layout is selected, amount of reserved memory can be
adjusted with -m or --socket-mem
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /run/user/1000/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'VA'
