This bug is awaiting verification that the linux-gcp-tcpx/6.8.0-1002.3 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-gcp-tcpx' to 'verification-done- jammy-linux-gcp-tcpx'. If the problem still exists, change the tag 'verification-needed-jammy-linux-gcp-tcpx' to 'verification-failed- jammy-linux-gcp-tcpx'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

Looks like the names changed slightly, thanks for pointing the the right
upstream commits!
And I see that they are marked as stable updates ("Cc: sta...@vger.kernel.org #
v6.7+"), which is great!
With that they will be soon automatically be picked up by the Canonical kernel
team.

[Bug 2070329] Re: KOP L2 guest fails to boot with 1 core - SMT8 topology (Fedora)
Hello and thanks for having reported this issue. Once the patch set 'Fix doorbell emulation for v2 API on PPC' with patches: - arch/powerpc/kvm: Add DPDES support in helper library for Guest state buffer - arch/powerpc/kvm: Fix doorbell emulation for v2 API are upstream accepted (having them in 'linux-next' is sufficient), we can think about picking them. I cannot find them in 'linux-next' yet (https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/log/?qt=grep&q=Fix+doorbell+emulation+for+v2+API), but assume they are still part of a staging tree and will hit linux-next soon. Based on your statement "The fix has been accepted upstream and will be backported for kernels >= 6.7" I assume the patch(es) are (or will be soon) also upstream marked as "stable updates", and will then land in kernel 6.8 (that we have in 24.04). As soon as this happens, the "stable updates" for 6.8 will be picked by the Canonical kernel team automatically. ** Also affects: ubuntu-power-systems Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) => (unassigned) ** Changed in: ubuntu-power-systems Assignee: (unassigned) => Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) ** Summary changed: - KOP L2 guest fails to boot with 1 core - SMT8 topology (Fedora) + KOP L2 guest fails to boot with 1 core - SMT8 topology ** Changed in: ubuntu-power-systems Importance: Undecided => High ** Changed in: linux (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2070329 Title: KOP L2 guest fails to boot with 1 core - SMT8 topology To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/2070329/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
