Package: crash Version: 7.2.3+real-2 Severity: normal Tags: upstream Dear Maintainer,
I experienced a crash with kdump-tools installed and wanted to report that crash (#919290). I tried to have a look at the collected core and found that crash gives an error message and exits (see below). This seems to be caused by recent changes in the current 4.19 series. As it looks like this may get the next stable kernel it would be nice if crash could analyze cores from that kernel. Upstream seem to have some fixes for 4.19 kernels [1]. I made a local build with [2] and [3] applied, and it did not fail anymore. Kind regards, Bernhard [1] https://people.redhat.com/anderson/crash.changelog.html [2] https://github.com/crash-utility/crash/commit/d7eec45d4c2cdd836ce48a81b0ae688a7d2879ba [3] https://github.com/crash-utility/crash/commit/001f77a05585c15ebd14bb72d5fde314a63c06fe Output of failing "crash": $ crash /usr/lib/debug/lib/modules/4.19.0-1-amd64/vmlinux /var/crash/201901141532/dump.201901141532 crash 7.2.3 Copyright (C) 2002-2017 Red Hat, Inc.
