There is no issue with 14.10 or 14.04. Kernel 4.0 do not help. dmesg when closing/opening with kernel "Linux alex-ThinkPad-T420s 3.19.0-7-generic #7-Ubuntu SMP Thu Feb 26 20:19:34 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux": [ 94.842668] systemd-logind[1262]: Lid closed. [ 102.468204] systemd-logind[1262]: Lid opened. [ 102.468661] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment [ 124.075694] systemd-logind[1262]: Removed session c1. The i915 seems to be unrelated: it appears after the lid is opened again, and "pci=noacpi" makes it disappear but the bug stays. I managed to got it to work, after playing with the e1000e driver as suggested on https://bbs.archlinux.org/viewtopic.php?pid=1414261#p1414261, but with a dubious and inconsistent state: - doing nothing, e1000e loaded, it never goes to suspend when I close the lid (tried 5 times) - removing e1000e, goes to suspend when I close the lid - doing nothing, e1000e removed, it again cannot go to suspend when I close the lid - loading e1000e, goes to suspend when I close the lid WORKAROUND: Manually suspend. --- ApportVersion: 2.16.2-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: alex 1914 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 15.04 InstallationDate: Installed on 2015-03-07 (0 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) MachineType: LENOVO 4171CTO Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.19.0-7-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.19.0-7.7-generic 3.19.0 Tags: vivid Uname: Linux 3.19.0-7-generic x86_64 UpgradeStatus: Upgraded to vivid on 2015-03-07 (0 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 07/18/2013 dmi.bios.vendor: LENOVO dmi.bios.version: 8CET58WW (1.38 ) dmi.board.asset.tag: Not Available dmi.board.name: 4171CTO dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr8CET58WW(1.38):bd07/18/2013:svnLENOVO:pn4171CTO:pvrThinkPadT420s:rvnLENOVO:rn4171CTO:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 4171CTO dmi.product.version: ThinkPad T420s dmi.sys.vendor: LENOVO --- ApportVersion: 2.16.2-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: alex 1914 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 15.04 InstallationDate: Installed on 2015-03-07 (0 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) MachineType: LENOVO 4171CTO Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.19.0-7-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.19.0-7.7-generic 3.19.0 Tags: vivid Uname: Linux 3.19.0-7-generic x86_64 UpgradeStatus: Upgraded to vivid on 2015-03-07 (0 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 07/18/2013 dmi.bios.vendor: LENOVO dmi.bios.version: 8CET58WW (1.38 ) dmi.board.asset.tag: Not Available dmi.board.name: 4171CTO dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr8CET58WW(1.38):bd07/18/2013:svnLENOVO:pn4171CTO:pvrThinkPadT420s:rvnLENOVO:rn4171CTO:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 4171CTO dmi.product.version: ThinkPad T420s dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1429489/+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
