Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 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.

I discovered this issue in a quiet room, where I could hear the clicks (or "death rattle", as I've come to think of them). The following commands will stop the load cycle problem: sudo hdparm -B 254 /dev/sda sudo hdparm -B 255 /dev/sda However, it is difficult to keep the system from reverting back to the load cycle problem. Steps to reproduce: 1. Boot the laptop on AC, then unplug the power. In a quiet room, you can hear the clicks begin soon after you unplug. 2. Boot the laptop on battery. Even with "apm = 255" uncommented in /etc/hdparm.conf, the laptop will burn through the load cycles until I manually perform the hdparm command. I had limited results with an upstart job that did the hdparm command -- but it wasn't a complete, reliable solution. It didn't catch the AC-to-battery power transition, for example. As a result of this issue, my hard drive is probably going to meet an early demise: 193 Load_Cycle_Count 0x0012 090 090 000 Old_age Always - 107908 Please help- Casey ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-32-generic 3.13.0-32.57 [modified: boot/vmlinuz-3.13.0-32-generic] ProcVersionSignature: Ubuntu 3.13.0-32.57-generic 3.13.11.4 Uname: Linux 3.13.0-32-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: cmars 2565 F.... pulseaudio CurrentDesktop: XFCE Date: Wed Jul 30 19:00:13 2014 InstallationDate: Installed on 2014-07-29 (1 days ago) InstallationMedia: Xubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140723) MachineType: LENOVO 2306CTO ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-32-generic root=UUID=fac0754b-bf8e-424a-9485-c1ea9825152f ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-3.13.0-32-generic N/A linux-backports-modules-3.13.0-32-generic N/A linux-firmware 1.127.5 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 07/09/2013 dmi.bios.vendor: LENOVO dmi.bios.version: G2ET95WW (2.55 ) dmi.board.asset.tag: Not Available dmi.board.name: 2306CTO dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrG2ET95WW(2.55):bd07/09/2013:svnLENOVO:pn2306CTO:pvrThinkPadX230:rvnLENOVO:rn2306CTO:rvrNotDefined:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 2306CTO dmi.product.version: ThinkPad X230 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1350620/+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
