Hello Kowshik, thanks for raising this! This is unfortunately one drawback of going with very recent kernel versions - some other packages (like makedumpfile here) may not have caught up.
The version we have in plucky/25.04: makedumpfile | 1:1.7.6-1 | plucky | source, amd64, arm64, armhf, ppc64el, riscv64, s390x is the latest upstream version: https://github.com/makedumpfile/makedumpfile/releases makedumpfile-1.7.6 And there are also no further commits yet in upstream (master, on top of 1.7.6) that extend the kernel support in any way: https://github.com/makedumpfile/makedumpfile/commits Since these messages are not critical, nor errors, we have to live with them until upstream extended the support to kernels that incl. 6.11. Once we are there, we can think about cherry-picking the corresponding commits and SRU them to the makedumpfile version of plucky. Please notice that once 25.04 - or any Ubuntu release - got officially published, we cannot simply bump packages to new versions (our SRU policy forbids us doing so), instead we selectively need to pick and choose (cherry-pick) any fixes... With that I am not closing this ticket, but update it to status "Invalid" (incl. support requests), and Importance "Medium", so that we can reconsider it once upstream was able to catch up on the supported kernel versions. ** Package changed: linux (Ubuntu) => makedumpfile (Ubuntu) ** Also affects: ubuntu-power-systems Importance: Undecided Status: New ** Changed in: ubuntu-power-systems Assignee: (unassigned) => Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) ** Changed in: ubuntu-power-systems Importance: Undecided => Medium ** Changed in: makedumpfile (Ubuntu) Importance: Undecided => Medium ** Changed in: ubuntu-power-systems Status: New => Opinion ** Changed in: makedumpfile (Ubuntu) Status: New => Invalid ** Changed in: ubuntu-power-systems Status: Opinion => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2105757 Title: [Ubuntu25.04] Unusual messages were seen on the console while trying KDump and FADump Status in The Ubuntu-power-systems project: Invalid Status in makedumpfile package in Ubuntu: Invalid Bug description: == Comment: #0 - Kowshik Jois B S <[email protected]> - 2025-03-05 03:05:04 == ---Problem Description--- Though dump is getting captured with both KDump and FADump, below messages were seen on the console when a crash is triggered with sysrq in both the cases.

These messages are expected and are printed via makedumpfile. The upstream makedumfile project is updated on regular basis to support newer upstream kernel releases. Until then the above mentioned messages are printed. README file included with the makedumpfile source code captures the kernel version it supports. Currently there is support till 6.11 kernel [v1.7.6] Update version Update makedumpfile to version 1.7.6. This version supports the following new kernels: - 6.9, 6.10, 6.11 (x86_64) https://github.com/makedumpfile/makedumpfile/blob/master/README#L175 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/2105757/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
