Expected behaviour: To reboot and NOT shutdown Impacted HW: HPE DL 380 OR Synergy 480 Gen 10 Plus Server 2P core count greater than 16 (like 24,28 or 32) Impacted OS: Ubuntu 22.04.2 kernel higher than 15.17.15 When the CPU count is 1, issue is not observed. When core count is less than 24 (like 16) issue not observed. [Fix] Problem introduced in v5.18 with commit: 08f253ec3767 x86/cpu: Clear SME feature flag when not in use Fixes for the above:0 9b040453d444 x86/smp: Dont access non-existing CPUID leaf 1f5e7eb7868e x86/smp: Make stop_other_cpus() more robust [Test Case] $ sudo reboot Server should reboot and not power off. [Where Problems Could Occur] The fixes modify x86 stop-CPU code so reboot/poweroff of x86 machines could be affected.
