nr_cpus=1 for KDump case has never worked before on ppc64. Mahesh tried fixing it but the maintainer had a few apprensions and rightly so. This fix doesn't work in all cases. Say, KVM host (baremetal with SMT off).. So, to start with, "nr_cpus=1" as default parameter instead of "maxcpus=1" for KDump kernel on ppc64, even with the kernel fix from Mahes was not a good idea, as it was not something that works always... IMHO, with no alternate and foolproof way to fix this in discussion yet, we can save the "nr_cpus=1" option as default for another day and stick with "maxcpus=1" for now. That was the intention behind this bug.. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828597 Title: KDump boot fails with nr_cpus=1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1828597/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
