Hi, thanks for opening a bug report! On an initial look at your logs, some lines I see are related to kernel lockdown: Lockdown: systemd-logind: hibernation is restricted; see man kernel_lockdown.7 Lockdown: swapper/0: hibernation is restricted; see man kernel_lockdown.7
This may explain why hibernation is not available. I also see nvme 0000:04:00.0: platform quirk: setting simple suspend but it's unclear what the significance of this is. To debug this, we should start by determining if the problem is upstream. Could you try a mainline kernel build? Our latest mainline build available for amd64 is 6.18.1 at https://kernel.ubuntu.com/mainline/v6.18.1/ Instructions for installing mainline kernels are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds If the problem is resolved on mainline, we will start looking at if there are fixes to backport or if an Ubuntu patch caused a regression. If you have any settings in your BIOS related to suspending, it might be worth posting the status of those as well. ** Changed in: linux (Ubuntu) Status: New => Triaged ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Ian Whitfield (ijwhitfield) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2137434 Title: Suspend / resume failure on Kubuntu 24.04, NVME with OPAL encryption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2137434/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
