** Description changed: + [Impact] + New upstream kernel versions, as those in linux-hwe package, require a newer makedumpfile to be supported. Otherwise, all copies fallback to copying the entire memory. + + [Test case] + kdump-tools has been installed, system rebooted, then crash trigerred and verified that a small dump file was present on /var/crash/. Tested on amd64 and ppc64le. + + [Regression potential] + Many other bug fixes have been included in the latest version of the package. The changes are supposed to fix these bugs, and have been tested as well. However, as the total of changes is not trivial, there is impact of regression that has been minimized by the tests done. Regression potential of not supporting older kernels has been tested with the kernels shipped on xenial and artful as well. + + + + ==================================================================== + == Comment: #0 - Hari Krishna Bathini <[email protected]> - 2018-01-30 10:46:53 == ---Problem Description--- update makedumpfile to latest version v1.6.3 that officially supports up to kernel version 4.14.8.
