Robert Shields, thank you for reporting this and helping make Ubuntu better.
As per http://support.lenovo.com/us/en/products/Laptops-and-netbooks /ThinkPad-Yoga-Series-laptops/ThinkPad- Yoga-15?tabName=Downloads&linkTrack=Mast:SubNav:Support:Drivers%20and%20Software|Drivers%20and%20Software&beta=false an update to your computer's buggy, insecure, and outdated BIOS is available (1.22). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-1.22 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1579066 Title: Error parsing PCC subspaces from PCCT --- On startup Status in linux package in Ubuntu: Incomplete Bug description: New install of Ubuntu 16.04 from Windows 10 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-21-generic 4.4.0-21.37 [modified: boot/vmlinuz-4.4.0-21-generic] ProcVersionSignature: Ubuntu 4.4.0-21.37-generic 4.4.6 Uname: Linux 4.4.0-21-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia_modeset nvidia ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: shieldrj 1781 F.... pulseaudio /dev/snd/controlC0: shieldrj 1781 F.... pulseaudio CurrentDesktop: Unity Date: Fri May 6 09:08:38 2016 EcryptfsInUse: Yes HibernationDevice: RESUME=UUID=3b95cab7-d12d-4d82-aad7-7b9697484746 InstallationDate: Installed on 2016-05-03 (2 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) MachineType: LENOVO 20DQ001LUS ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-21-generic root=UUID=8a46bfbe-3fd3-4c14-b860-40af27c8c96b ro quiet splash RelatedPackageVersions: linux-restricted-modules-4.4.0-21-generic N/A linux-backports-modules-4.4.0-21-generic N/A linux-firmware 1.157 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/25/2015 dmi.bios.vendor: LENOVO dmi.bios.version: N19ET35W (1.08 ) dmi.board.asset.tag: Not Available dmi.board.name: 20DQ001LUS dmi.board.vendor: LENOVO dmi.board.version: SDK0E50510 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN19ET35W(1.08):bd03/25/2015:svnLENOVO:pn20DQ001LUS:pvrThinkPadS5Yoga15:rvnLENOVO:rn20DQ001LUS:rvrSDK0E50510WIN:cvnLENOVO:ct10:cvrNone: dmi.product.name: 20DQ001LUS dmi.product.version: ThinkPad S5 Yoga 15 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1579066/+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
