Would it be possible for you to do a kernel bisection? First, find the last good -rc kernel and the first bad -rc kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Then, $ sudo apt build-dep linux $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd linux $ git bisect start $ git bisect good $(the good version you found) $ git bisect bad $(the bad version found) $ make localmodconfig $ make -j`nproc` deb-pkg Install the newly built kernel, then reboot with it. If the issue still happens, $ git bisect bad Otherwise, $ git bisect good Repeat to "make -j`nproc` deb-pkg" until you find the commit that causes the regression. -- 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/1803246 Title: Ubuntu 18.10 is Unable to Suspend When Closing Lenovo E531 Laptop Lid Status in linux package in Ubuntu: Incomplete Bug description: The trackpad of my Lenovo E531 Thinkpad Edge works when logged into 18.10. When you close the lid the laptop normally goes into suspend (in 18.04), but fails to suspend in 18.10. The trackpad becomes unresponsive after the lid has been closed and the lid is opened again. See the response from dmesg below. Funny thing: This error does not occur when the power button is pressed and the trackpad is responsive (because a suspend was not attempted via the lid). I am using version: Ubuntu 4.18.0-10.11-generic 4.18.12 According to dmesg: [ 650.163700] Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done. [ 650.165107] Suspending console(s) (use no_console_suspend to debug) [ 650.165646] rmi4_f03 rmi4-00.fn03: rmi_f03_pt_write: Failed to write to F03 TX register (-6).

It would be great if 18.10 could suspend when the lid is closed. --- ProblemType: Bug ApportVersion: 2.20.10-0ubuntu13.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: anthony 5917 F.... pulseaudio CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.10 InstallationDate: Installed on 2018-06-24 (142 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) MachineType: LENOVO 68853EM NonfreeKernelModules: nvidia_modeset nvidia wl Package: linux (not installed) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_AU.UTF-8 SHELL=/bin/bash ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.18.0-10-generic root=UUID=40873332-4c5a-4f82-b0a4-c88bb092b9c6 ro quiet splash vt.handoff=1 ProcVersionSignature: Ubuntu 4.18.0-10.11-generic 4.18.12 RelatedPackageVersions: linux-restricted-modules-4.18.0-10-generic N/A linux-backports-modules-4.18.0-10-generic N/A linux-firmware 1.175 Tags: wayland-session cosmic Uname: Linux 4.18.0-10-generic x86_64 UpgradeStatus: Upgraded to cosmic on 2018-11-04 (9 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo vboxusers _MarkForUpload: True dmi.bios.date: 06/21/2018 dmi.bios.vendor: LENOVO dmi.bios.version: HEET52WW (1.33 ) dmi.board.asset.tag: Not Available dmi.board.name: 68853EM dmi.board.vendor: LENOVO dmi.board.version: Win8 Pro DPK TPG dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrHEET52WW(1.33):bd06/21/2018:svnLENOVO:pn68853EM:pvrThinkPadEdgeE531:rvnLENOVO:rn68853EM:rvrWin8ProDPKTPG:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.family: ThinkPad Edge E531 dmi.product.name: 68853EM dmi.product.sku: LENOVO_MT_6885_BU_Think_FM_ThinkPad Edge E531 dmi.product.version: ThinkPad Edge E531 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1803246/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
