I have used the steps outlined in https://wiki.ubuntu.com/Testing/EnableProposed documentation how to enable and use -proposed however, the kernel is not getting updated and still see the reboot issue.
Steps followed: 1) Took an HPE DL360 Gen 10 Plus system running 5.19 kernel (5.19.0-051900) where the issue is observed & confirmed the reboot issue. 2) Followed the instructions to enable the Jammy-proposed a) Verified using the GUI 'Software updater' in 'Developer Options' tab to ensure "Pre-released updates (jammy-proposed)" is checked. b) Made sure the /etc/opt/sources.list has "deb http://us.archive.ubuntu.com/ubuntu jammy-proposed main restricted universe multiverse" is added to the file 3) Performed an update using the following commands: sudo apt-get update sudo apt-get upgrade 4) Rebooted the system & tried to verify: a) the reboot problem still exists b) the kernel version is 5.19.0-051900-generic FYI - Normally the following steps are taken to update the kernel: Open Terminal cd ~/Downloads wget -c https://kernel.ubuntu.com/~kernel- ppa/mainline/v5.19/amd64/linux- headers-5.19.0-051900_5.19.0-051900.202207312230_all.deb wget -c https://kernel.ubuntu.com/~kernel- ppa/mainline/v5.19/amd64/linux- headers-5.19.0-051900-generic_5.19.0-051900.202207312230_amd64.deb wget -c https://kernel.ubuntu.com/~kernel- ppa/mainline/v5.19/amd64/linux-image- unsigned-5.19.0-051900-generic_5.19.0-051900.202207312230_amd64.deb wget -c https://kernel.ubuntu.com/~kernel- ppa/mainline/v5.19/amd64/linux- modules-5.19.0-051900-generic_5.19.0-051900.202207312230_amd64.deb sudo apt install ./linux-headers-5.19.0*.deb ./linux-image- unsigned-5.19.0*.deb ./linux-modules-5.19.0*.deb -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.2 in Ubuntu. https://bugs.launchpad.net/bugs/2029332 Title: Reboot command powers off the system Status in linux package in Ubuntu: Confirmed Status in linux-hwe-6.2 package in Ubuntu: Confirmed Status in linux-hwe-6.2 source package in Jammy: Fix Released Status in linux source package in Lunar: Fix Committed Bug description: [Impact] Issue: When a reboot (or init 6) command is issued the server shuts down instead. 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.
