Ok, now I am going to look really stupid now, but last night after reporting the issue here I got a Lenovo BIOS/UEFI firmware update notification for the laptop (was on 0.1.7 asking me to upgrade to 0.1.8).
I upgraded and retested. I retested it today for the duration of the day just to be sure and I can confirm that there is no longer an issue with firmware 0.1.8 thus far. I know it looks silly, but I had seriously tested it, before there was an update, to make sure I do not open a rubbish report here; there was 100% an issue with suspend on 0.1.7 specifically on the Ubuntu installation. I will attach system logs as requested anyway, just in case there is something there that is of value. Sorry for wasting your time if this proves to be a dud. ** Tags added: apport-collected wayland-session ** Description changed: I am running a new installation of Ubuntu noble 24.04 x86_64 (kernel 6.8.0-45-generic) on a brand new Thinkpad T14 Gen 5 (AMD Ryzen 7 PRO 8840U w/ Radeon 780M Graphics (16) @ 6.08 GHz) The machine does not suspend properly, which I noticed after returning from work with it in my backpack, taking it out and it was hot. While suspended the screen is in fact off, and the relevant LEDs enter a "breath" mode, indicating a suspended state, but there is an audible mechanical "tick" sound coming from the bottom, where I suppose the fan is located, and the laptop produces heat (gets hot if it's in a closed environment like my backpack) At first I thought it was a "lid closed" issue, but after further experimentation turns out that it's not a lid issue, but rather a suspension issue; suspending from the power button has the same result I could not reproduce this behaviour on Windows (I am dual booting, Windows Fastboot is off btw); suspending works properly; tested it, no "tick" sound, no heat. P.S. for what it's worth, my Thinkpad x13 Gen 1 on ubuntu 22, same kernel version on AMD Ryzen Pro 7 4750U, has no issues with suspend. Attaching system specs below. Please let me know what other info I need to provide Thanks. + --- + ProblemType: Bug + ApportVersion: 2.28.1-0ubuntu3.1 + Architecture: amd64 + CRDA: N/A + CasperMD5CheckResult: pass + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 24.04 + InstallationDate: Installed on 2024-09-29 (3 days ago) + InstallationMedia: Ubuntu 24.04.1 LTS "Noble Numbat" - Release amd64 (20240827.1) + MachineType: LENOVO 21MCS06F00 + Package: linux (not installed) + ProcEnviron: + LANG=en_US.UTF-8 + PATH=(custom, no user) + SHELL=/bin/bash + TERM=xterm-256color + XDG_RUNTIME_DIR=<set> + ProcFB: 0 amdgpudrmfb + ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-6.8.0-45-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro quiet splash vt.handoff=7 + ProcVersionSignature: Ubuntu 6.8.0-45.45-generic 6.8.12 + RelatedPackageVersions: + linux-restricted-modules-6.8.0-45-generic N/A + linux-backports-modules-6.8.0-45-generic N/A + linux-firmware 20240318.git3b128b60-0ubuntu2.4 + Tags: noble wayland-session + Uname: Linux 6.8.0-45-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sudo users + _MarkForUpload: True + dmi.bios.date: 08/07/2024 + dmi.bios.release: 1.8 + dmi.bios.vendor: LENOVO + dmi.bios.version: R2LET27W (1.08 ) + dmi.board.asset.tag: Not Available + dmi.board.name: 21MCS06F00 + dmi.board.vendor: LENOVO + dmi.board.version: SDK0T76530 WIN + dmi.chassis.asset.tag: No Asset Tag + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: None + dmi.ec.firmware.release: 1.4 + dmi.modalias: dmi:bvnLENOVO:bvrR2LET27W(1.08):bd08/07/2024:br1.8:efr1.4:svnLENOVO:pn21MCS06F00:pvrThinkPadT14Gen5:rvnLENOVO:rn21MCS06F00:rvrSDK0T76530WIN:cvnLENOVO:ct10:cvrNone:skuLENOVO_MT_21MC_BU_Think_FM_ThinkPadT14Gen5: + dmi.product.family: ThinkPad T14 Gen 5 + dmi.product.name: 21MCS06F00 + dmi.product.sku: LENOVO_MT_21MC_BU_Think_FM_ThinkPad T14 Gen 5 + dmi.product.version: ThinkPad T14 Gen 5 + dmi.sys.vendor: LENOVO -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2083454 Title: Suspend issue with AMD Ryzen 8840U CPU and kernel 6.8.0-45-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2083454/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
