Public bug reported: Suspend stopped working when upgraded to kernel 5.3.0-41 from -40. Power-button (narrow slit) LED stays fully lit and front indicator power/wifi/drive LEDs also lit as though not suspended. Screen went black but will not respond to keyboard/touchpad input (even Ctrl-Alt- Del). Only way to recover laptop was long-press power button (5 seconds) to force it to turn off then press again as normal to cold boot.
Also note: Builtin stereo speakers also stopped working in the same kernel version change - out of scope for this bug I expect, perhaps related to SOF or Alsa migration/integration changes I saw in changelog: Builtin microphone never worked on 19.10, even after researching issue and trying assigning each pin in turn to it via hdajackretask. Boot and shutdown and suspend and builtin speakers all working normally in kernels from initial install of 19.10 in November 2019 through 5.3.0-40 (inclusive). Laptop is an HP Elitebook 830 G6 with ProdId 6XE61EA#... TRIED: installed 5.3.0-42 (latest as I write) kernel, same result as -41. Added "snd_hda_intel.dmic_detect=0" to /etc/modprobe.d/alsa.conf (about to try it in alsa-base.conf instead) Also tried live boot of daily snapshot of Ubuntu 20.04 from 12 March 2020, fails to suspend and speakers not recognised (same problems). Kern.log and LEDs strongly indicate machine crashes before suspend achieved (having read up on the difference), so appears to be a suspend problem not a resume one; especially as LED goes into dim/brighten cycle on previous kernels when it goes into suspend and resumes fully with no issue. Cancelling the suspend just after I've pressed the power button to suspend it and the screen has gone black (think I used space key? or did I press power again?) worked the one time I tried it, and dmesg/logs indicate a fair bit of the suspend happens ok. Appears to match part of this upstream issue (about an HP Spectre x360 laptop): https://bugzilla.kernel.org/show_bug.cgi?id=205959 May have time to bisect some kernel changes or try other fixes or build kernels/code, given a few days (am a software developer) ProblemType: Bug DistroRelease: Ubuntu 19.10 Package: linux-image-5.3.0-42-generic 5.3.0-42.34 ProcVersionSignature: Ubuntu 5.3.0-42.34-generic 5.3.18 Uname: Linux 5.3.0-42-generic x86_64 ApportVersion: 2.20.11-0ubuntu8.5 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CurrentDesktop: ubuntu:GNOME Date: Fri Mar 13 19:12:23 2020 InstallationDate: Installed on 2019-11-08 (126 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) MachineType: HP HP EliteBook 830 G6 ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.3.0-42-generic root=UUID=4eabc89a-3237-4e0b-91b2-56346c65d607 ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-5.3.0-42-generic N/A linux-backports-modules-5.3.0-42-generic N/A linux-firmware 1.183.4 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 06/18/2019 dmi.bios.vendor: HP dmi.bios.version: R70 Ver. 01.02.00 dmi.board.name: 854A dmi.board.vendor: HP dmi.board.version: KBC Version 52.4C.00 dmi.chassis.asset.tag: 5CG9381HTF dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.modalias: dmi:bvnHP:bvrR70Ver.01.02.00:bd06/18/2019:svnHP:pnHPEliteBook830G6:pvr:rvnHP:rn854A:rvrKBCVersion52.4C.00:cvnHP:ct10:cvr: dmi.product.family: 103C_5336AN HP EliteBook dmi.product.name: HP EliteBook 830 G6 dmi.product.sku: 6XE61EA#ABU dmi.sys.vendor: HP ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug eoan package-from-proposed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867388 Title: suspend crashes laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1867388/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
