Black Wolf, as per http://support.lenovo.com/us/en/products/laptops-and- netbooks/lenovo-b-series-laptops/lenovo-b575e-notebook an update to your computer's buggy and outdated BIOS is available (1.07). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 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. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-1.07 ** Changed in: linux (Ubuntu) Status: Confirmed =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/1421212 Title: Bluetooth working randomly Status in linux package in Ubuntu: Incomplete Bug description: Bluetooth is working randomly, at boot sometimes gives Bluetooth: hci0 sending frame failed Ubuntu 14.04 LTS, update uname -a $ Lenovo-B575e 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux lspci | grep Wireless $ Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01) dmesg log diff boot_notworking.log bootworking.log| grep luetooth < [ 17.946819] thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked < [ 18.890810] Bluetooth: Core ver 2.17 < [ 18.890860] Bluetooth: HCI device and connection manager initialized < [ 18.890878] Bluetooth: HCI socket layer initialized < [ 18.890884] Bluetooth: L2CAP socket layer initialized < [ 18.890894] Bluetooth: SCO socket layer initialized < [ 20.002871] Bluetooth: can't load firmware, may not work correctly < [ 20.006422] Bluetooth: hci0 sending frame failed < [ 21.030518] Bluetooth: RFCOMM TTY layer initialized < [ 21.030549] Bluetooth: RFCOMM socket layer initialized < [ 21.030574] Bluetooth: RFCOMM ver 1.11 < [ 21.121526] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 < [ 21.121537] Bluetooth: BNEP filters: protocol multicast < [ 21.121558] Bluetooth: BNEP socket layer initialized > [ 12.956963] thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked > [ 13.348060] Bluetooth: Core ver 2.17 > [ 13.348118] Bluetooth: HCI device and connection manager initialized > [ 13.348136] Bluetooth: HCI socket layer initialized > [ 13.348142] Bluetooth: L2CAP socket layer initialized > [ 13.348152] Bluetooth: SCO socket layer initialized > [ 14.270573] Bluetooth: can't load firmware, may not work correctly > [ 21.295073] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 > [ 21.295083] Bluetooth: BNEP filters: protocol multicast > [ 21.295104] Bluetooth: BNEP socket layer initialized > [ 21.319534] Bluetooth: RFCOMM TTY layer initialized > [ 21.319565] Bluetooth: RFCOMM socket layer initialized > [ 21.319590] Bluetooth: RFCOMM ver 1.11 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-45-generic 3.13.0-45.74 ProcVersionSignature: Ubuntu 3.13.0-45.74-generic 3.13.11-ckt13 Uname: Linux 3.13.0-45-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.14.1-0ubuntu3.6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: walter 1975 F.... pulseaudio /dev/snd/controlC0: walter 1975 F.... pulseaudio CurrentDesktop: Unity Date: Thu Feb 12 14:35:42 2015 HibernationDevice: RESUME=UUID=d07e5522-cadf-4724-8aa4-b4411094fbaa InstallationDate: Installed on 2014-08-01 (195 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: LENOVO 36852BG ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-45-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-3.13.0-45-generic N/A linux-backports-modules-3.13.0-45-generic N/A linux-firmware 1.127.11 SourcePackage: linux StagingDrivers: rts5139 UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 12/26/2012 dmi.bios.vendor: LENOVO dmi.bios.version: HPET68WW(1.06) dmi.board.asset.tag: Not Available dmi.board.name: 36852BG 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:bvrHPET68WW(1.06):bd12/26/2012:svnLENOVO:pn36852BG:pvrLenovoB575e:rvnLENOVO:rn36852BG:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 36852BG dmi.product.version: Lenovo B575e dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1421212/+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
