Hello Dave, At least on s390 the latest crash version 7.1 does not work with kernels >= 4.0: WARNING: kernels compiled by different gcc versions: /boot/vmlinux: (unknown) vmcore kernel: 4.9.2 WARNING: kernel version inconsistency between vmlinux and dumpfile crash: incompatible arguments: /boot/vmlinux is not SMP -- vmcore is SMP The git master branch seems to have a patch that solves this problem. IMO it would be good to have a new crash release with that fix. What do you think? Michael -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
