---Problem Description--- kexec fails in LPAR when some cpus are disabled Contact Information = sthou...@in.ibm.com Machine Type = na ---uname output--- na ---Debugger--- A debugger is not configured ---Steps to Reproduce--- Summary: At L1 level, kexec fails if some of the cpus in the machine are disabled. Distros and kernel versions used: 1. Distro versions used a. L1 LPAR : b. L2 : Repro steps: 1. Boot into an L1 lpar 2. Disable some cpus (eg: ppc64_cpu --cores-on=3) 3. Try to kexec. This bug is reproducible only when we load the target kernel/initrd and use "kexec -e" as follows: kexec -l --initrd initramfs-$(uname -r).img vmlinuz-$(uname -r) --append="$(cat /proc/cmdline)" kexec -e kexec works fine if we do a normal kexec without skipping the shutdown path kexec --initrd initramfs-$(uname -r).img vmlinuz-$(uname -r) --append="$(cat /proc/cmdline)" Fix is upstream now: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?id=21a741eb75f80397e5f7d3739e24d7d75e619011 Thanks, Sourabh Jain please include in Ubuntu Oops output: no Stack trace output: no System Dump Info: The system is not configured to capture a system dump. *Additional Instructions for sthou...@in.ibm.com: -Attach sysctl -a output output to the bug. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) Status: New ** Tags: architecture-ppc64le bugnameltc-208048 severity-high targetmilestone-inin--- -- kexec fails in LPAR when some cpus are disabled https://bugs.launchpad.net/bugs/2075575 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
