hi penalvch and jsalisbury, rc3 kernel did not solve the problem, the shutdown and reboot loop has started again. My machine was working normally for the next couple of shutdowns but it started again from the last night. So, I am modifying the tag as 'kernel-bug-exists-upstream' (according to jsalisbury's suggession)
I will test with http://cdimage.ubuntu.com/daily-live/current/ and let you know what I get. ** Tags removed: kernel-fixed-upstream ** Tags added: kernel-bug-exists-upstream -- 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/1261886 Title: [Lenovo ThinkPad S431] Boots up after shutdown Status in “linux” package in Ubuntu: Incomplete Bug description: I first removed the ~/.Xauthority file it worked fine for the next two-three shutdowns, then it started again. Then I added acpi=noirq switch in the kernel parameter and seemed to be fixed for couple of weeks, then it started again. Moreover, after acpi=noirq, the bluetooth has stopped working. Moreover, I also tried to remove the module ehci_hcd by this command -- rmmod ehci_hcd but I failed to make this work. details can be found here -- http://www.thinkwiki.org/wiki/How_to_make_ACPI_work#Machine_reboots_after_shutting_down This is also (most probably) similar to this Bug 1230359 ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: linux-image-3.11.0-14-generic 3.11.0-14.21 ProcVersionSignature: Ubuntu 3.11.0-14.21-generic 3.11.7 Uname: Linux 3.11.0-14-generic x86_64 ApportVersion: 2.12.5-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: khaled 2676 F.... pulseaudio Date: Tue Dec 17 15:03:26 2013 HibernationDevice: RESUME=UUID=febf0c2e-7d67-4ccf-b968-a069097b696a InstallationDate: Installed on 2013-11-26 (20 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: LENOVO 20AXCTO1WW MarkForUpload: True ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.11.0-14-generic.efi.signed root=UUID=9746bcf4-275a-4e5a-8ddd-8efec0a455f5 ro RelatedPackageVersions: linux-restricted-modules-3.11.0-14-generic N/A linux-backports-modules-3.11.0-14-generic N/A linux-firmware 1.116 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 07/10/2013 dmi.bios.vendor: LENOVO dmi.bios.version: HFET30WW (1.07 ) dmi.board.asset.tag: Not Available dmi.board.name: 20AXCTO1WW 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:bvrHFET30WW(1.07):bd07/10/2013:svnLENOVO:pn20AXCTO1WW:pvrThinkPadS3-S431:rvnLENOVO:rn20AXCTO1WW:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20AXCTO1WW dmi.product.version: ThinkPad S3-S431 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1261886/+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
