Public bug reported:
Original Setting for Ubuntu 16.04 :
cat config-4.4.0-59-generic | grep NUMA
CONFIG_ARCH_SUPPORTS_NUMA_BALANCING=y
CONFIG_NUMA_BALANCING=y
# CONFIG_NUMA_BALANCING_DEFAULT_ENABLED is not set
CONFIG_NUMA=y
# Select NUMA modes
CONFIG_NUMA_EMU=y
Than changed with Ubuntu 16.10 to
$ grep NUMA config-4.8.0-30-generic
CONFIG_ARCH_SUPPORTS_NUMA_BALANCING=y
# CONFIG_NUMA is not set
Changed again with Ubuntu 17.04 back to original
grep NUMA config-4.9.0-15-generic
CONFIG_ARCH_SUPPORTS_NUMA_BALANCING=y
CONFIG_NUMA_BALANCING=y
# CONFIG_NUMA_BALANCING_DEFAULT_ENABLED is not set
CONFIG_NUMA=y
# Select NUMA modes
CONFIG_NUMA_EMU=y
The setting for 16.10 and also for 16.04.2 should be changed to the
original once
