Package: crash Version: 7.2.5-1 Severity: grave Justification: renders package unusable
Dear Maintainer, I set up a fresh Debian 10 install on my i686 machine today. I installed 'kdump-tools' and 'crash' I added 'kernel.softlockup_panic=1' and 'kernel.hardlockup_panic=1' to /etc/sysctl.conf I rebooted so kdump-tools would add the 'crashkernel=384M-:128M' argument to my kernel command line I then triggered a crash by running 'sysctl kernel.sysrq=1 && echo c > /proc/sysrq-trigger' It saved a crash to '/var/crash/202002270816/dump.202002270816' I installed 'linux-image-4.19.0-8-686-pae-dbg' I ran 'crash /usr/lib/debug/vmlinux-4.19.0-8-686-pae /var/crash/202002270816/dump.202002270816' The following output happened: ---- CUT HERE ---- crash 7.2.5 Copyright (C) 2002-2019 Red Hat, Inc.
