Yes, 5.15.0-152 from proposed does not contain the patch with the potential fix.
I created a test kernel, version 5.15.0-152.163~lp2118407, which is the same as 5.15.0-152 with the addition of commit https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.15.y&id=32caa50275cc52a382ca77b53ce3d6204d509e14. You can find it in the PPA at https://launchpad.net/~kevinbecker/+archive/ubuntu/lp2118407 You can install this kernel with the following commands: sudo add-apt-repository ppa:kevinbecker/lp2118407 sudo apt update sudo apt upgrade Then reboot and you should be running the test kernel. Once installed an running, you can confirm the kernel via `uname -a`. Here's an example output with the test kernel: ~$ uname -a Linux jammy-lp2118407 5.15.0-152-generic #163~lp2118407-Ubuntu SMP Thu Jul 31 20:16:28 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux Please see if this kernel fixes your issue. ** Changed in: linux (Ubuntu) Status: Confirmed => In Progress ** Changed in: linux (Ubuntu Jammy) Status: Confirmed => In Progress ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Kevin Becker (kevinbecker) ** Changed in: linux (Ubuntu Jammy) Assignee: (unassigned) => Kevin Becker (kevinbecker) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2118407 Title: watchdog: BUG: soft lockup - CPU#6 stuck for 5718s!
