Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.16 stable kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Instead I have to power off manually by holding the power button for some seconds. Resuming from hibernation does work reliably however. This is regression, since it works perfectly with the utopic kernel (currently 3.16.0.31.24). To be more precise, the standard 'platform' mode causes this issue: echo platform > /sys/power/disk echo disk > /sys/power/state When using the 'shutdown' mode the system powers off correctly: echo shutdown > /sys/power/disk echo disk > /sys/power/state ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: linux-image-3.19.0-9-generic 3.19.0-9.9 [modified: boot/vmlinuz-3.19.0-9-generic] ProcVersionSignature: Ubuntu 3.19.0-9.9-generic 3.19.1 Uname: Linux 3.19.0-9-generic x86_64 ApportVersion: 2.16.2-0ubuntu3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: kiran 1458 F.... pulseaudio CurrentDesktop: XFCE Date: Sat Mar 14 19:36:16 2015 HibernationDevice: RESUME=UUID=ebcf26a9-f63a-4b55-ad87-31f7b1f3feb6 InstallationDate: Installed on 2015-03-14 (0 days ago) InstallationMedia: Xubuntu 15.04 "Vivid Vervet" - Alpha amd64 (20150313) MachineType: LENOVO 2767WSD PccardctlIdent: Socket 0: no product info available PccardctlStatus: Socket 0: no card ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.19.0-9-generic root=UUID=f0d3de75-e584-48c4-a3af-7b73dd5eb495 ro quiet splash RelatedPackageVersions: linux-restricted-modules-3.19.0-9-generic N/A linux-backports-modules-3.19.0-9-generic N/A linux-firmware 1.143 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no SourcePackage: linux UdevLog: Error: [Errno 2] No such file or directory: '/var/log/udev' UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/17/2012 dmi.bios.vendor: LENOVO dmi.bios.version: 7UET94WW (3.24 ) dmi.board.name: 2767WSD 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:bvr7UET94WW(3.24):bd10/17/2012:svnLENOVO:pn2767WSD:pvrThinkPadT400:rvnLENOVO:rn2767WSD:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 2767WSD dmi.product.version: ThinkPad T400 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1432222/+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
