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 ------- Comment From heinz-werner_se...@de.ibm.com 2017-02-06 09:24 EDT------- *** Bug 151232 has been marked as a duplicate of this bug. *** ** Tags added: architecture-s39064 bugnameltc-151262 severity-high targetmilestone-inin1610 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1661620 Title: CONFIG_NUMA is missing from the 4.8 kernels on s390x Status in Ubuntu on IBM z Systems: Triaged Status in linux package in Ubuntu: Invalid Status in linux-hwe-edge package in Ubuntu: Invalid Status in linux source package in Xenial: Invalid Status in linux-hwe-edge source package in Xenial: Triaged Status in linux source package in Yakkety: Triaged Status in linux-hwe-edge source package in Yakkety: Invalid Bug description: CONFIG_NUMA is not set in the 4.8 kernels (16.10 & linux-edge) when it should have been, on s390x.
