Attaching .debdiff to this comment for SRU sponsorship consideration into Eoan.
** Patch added: "makedumpfile_1.6.5-1ubuntu3.1.debdiff" https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1741860/+attachment/5279278/+files/makedumpfile_1.6.5-1ubuntu3.1.debdiff ** Description changed: + [Impact] + + * The value chosen for ppc64el of 128MB aligns with that of the kernel + default. That may change some day, so it would be best to let the kernel + decide what value it should use. If the value does change and the kernel + is not allowed to choose a value, this may stop the kernel from booting + on a production system. + + [Test Case] + + Run `cat /etc/default/grub.d/kdump-tools.cfg` + + * Expected result: there is no offset specified at the end of the line + (.e.g, @128M). + + * Actual result: For Xenial, Bionic, Disco, and Eoan there are offsets + specified. + + [Regression Potential] + + * Right now, the offset described in the kdump-tools.cfg aligns with + that of what the kernel would select, so since they are the same we + would expect no change in operation. + + + Original bug description follows: + ----------------------------------------- + == Comment: #0 - Hari Krishna Bathini <hbath...@in.ibm.com> - 2018-01-08 01:06:41 == ---Problem Description--- A default offset of 128MB is enforced for crashkernel by kdump-tools utility overriding the kernel default.
