Couple of thoughts, which we probably should get IBM's advice on: I believe this is using: crashkernel=384M-:128M
128M reserved seems too small for so much memory, tbh. Also, I see that all the CPUs are on in the crashkernel, when realistically only 1 CPU is needed (and there have been issues in the past with SMP in the kdump kernel, iirc). Finally, 'kvm_cma: CMA: failed to reserve 128 MiB' probably indicates we should pass kvm_cma_resv_ratio=0 to the kdump kernel (we're never going to run guests in the kdump environment). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567539 Title: Failure to dump with trusty+3.16 on ppc64el To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1567539/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
