** Description changed: Since the upgrade to 4.15.0-56-generic (Ubuntu 18.04), my computer fails to suspend. Suspend still works fine if I boot with previous kernel (4.15.0-55-generic). Looking at the changelog, I suspect the following change to be the cause of this regression: >> - usb: xhci: Prevent bus suspend if a port connect change or polling state is detected Indeed, my dmesg is also spammed all the time with USB failures and I would not be surprised that this change disallows suspending just because something is happening on my USB bus. Below, example of spam I often see in my journal: [ 55.772109] usb 2-5: new full-speed USB device number 14 using xhci_hcd [ 55.900048] usb 2-5: device descriptor read/64, error -71 [ 56.136052] usb 2-5: device descriptor read/64, error -71 (this repeats a lot of times, the device number is incremented every time) By the way, lsusb does not list any device on usb 2-5. - Of course, I may be wrong about the causal relation between all these - observations but it does not look all too much harebrained to me. + Of course, I may be wrong about the causal relation between all these observations but it does not look all too much harebrained to me. + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.7 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: aldric 16562 F.... pulseaudio + /dev/snd/controlC0: aldric 16562 F.... pulseaudio + CurrentDesktop: KDE + DistroRelease: KDE neon 18.04 + HibernationDevice: RESUME=UUID=ea5c7495-cd92-424b-b6a8-99b0fca30f1c + InstallationDate: Installed on 2014-10-21 (1744 days ago) + InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Alpha amd64 (20140923) + MachineType: Hewlett-Packard HP EliteBook 840 G1 + Package: linux (not installed) + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-55-generic root=UUID=01d6fe07-8259-4ecf-b862-6ea0c432a92b ro allow-discards root_trim=yes quiet splash drm.rnodes=1 + ProcVersionSignature: Ubuntu 4.15.0-55.60-generic 4.15.18 + RelatedPackageVersions: + linux-restricted-modules-4.15.0-55-generic N/A + linux-backports-modules-4.15.0-55-generic N/A + linux-firmware 1.173.10 + Tags: bionic + Uname: Linux 4.15.0-55-generic x86_64 + UpgradeStatus: Upgraded to bionic on 2018-09-19 (314 days ago) + UserGroups: adm cdrom dip input kvm lpadmin plugdev sambashare sudo users video wireshark + _MarkForUpload: True + dmi.bios.date: 07/28/2014 + dmi.bios.vendor: Hewlett-Packard + dmi.bios.version: L71 Ver. 01.20 + dmi.board.name: 198F + dmi.board.vendor: Hewlett-Packard + dmi.board.version: KBC Version 15.55 + dmi.chassis.asset.tag: 5CG4415D4J + dmi.chassis.type: 10 + dmi.chassis.vendor: Hewlett-Packard + dmi.modalias: dmi:bvnHewlett-Packard:bvrL71Ver.01.20:bd07/28/2014:svnHewlett-Packard:pnHPEliteBook840G1:pvrA3008CD10003:rvnHewlett-Packard:rn198F:rvrKBCVersion15.55:cvnHewlett-Packard:ct10:cvr: + dmi.product.family: 103C_5336AN G=N L=BUS B=HP S=ELI + dmi.product.name: HP EliteBook 840 G1 + dmi.product.version: A3008CD10003 + dmi.sys.vendor: Hewlett-Packard ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1838514/+attachment/5280147/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838514 Title: Suspend failure with kernel 4.15.0-56-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838514/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
