Package: crash Version: 7.0.8-1 Followup-For: Bug #699367 Dear Maintainer,
I have found that crash(8) fails in a similar manor when trying to analyse Linux 4.x kernel kdumps, see below for the "is not SMP" error: $ sudo crash /usr/lib/debug/boot/vmlinux-4.0.0-1-amd64 /var/crash/201505221035/dump.201505221035 crash 7.0.8 Copyright (C) 2002-2014 Red Hat, Inc.

Neither of these patches have made it into the current 7.1.0 release.

I assume once a new version of crash is released it will start working on sid and testing with time. However this info might prove useful to anyone trying and failing to inspect Linux 4.x kdump files.
