Observing the issue on Fedora 29 Cinnamon. I have Lenovo T440P laptop on which I am trying to connect my Bluetooth headsets (Sony MDR-XB650BT).
The Bluetooth is failing to even detect the headsets. At the same time, it can detect my smart bands, mobile phones, other laptops etc. The same headphones connect correctly on my Windows laptop. In dmesg, I can see the messages as : [717817.195781] Bluetooth: hci0: read Intel version: 3707100180012d0d00 [717817.198527] Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.7.10-fw-1.80.1.2d.d.bseq [717817.394926] Bluetooth: hci0: Intel firmware patch completed and activated [717818.100820] Bluetooth: hci0: last event is not cmd complete (0x0f) [717849.196840] Bluetooth: hci0: last event is not cmd complete (0x0f) [717906.393910] Bluetooth: hci0: last event is not cmd complete (0x0f) [717922.201017] Bluetooth: hci0: last event is not cmd complete (0x0f) -- 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/1748565 Title: Kernel regularly logs: Bluetooth: hci0: last event is not cmd complete (0x0f) Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed Status in Fedora: New Bug description: Hello, dmesg: [ 3363.056494] Bluetooth: hci0: last event is not cmd complete (0x0f) Regards, -- Cristian ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-9-generic 4.15.0-9.10 ProcVersionSignature: Ubuntu 4.15.0-9.10-generic 4.15.2 Uname: Linux 4.15.0-9-generic x86_64 ApportVersion: 2.20.8-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: caravena 1811 F.... pulseaudio CurrentDesktop: ubuntu-communitheme:ubuntu:GNOME Date: Fri Feb 9 20:35:29 2018 InstallationDate: Installed on 2017-10-13 (119 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Alpha amd64 (20170926) MachineType: SAMSUNG ELECTRONICS CO., LTD. 530U3C/530U4C ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/@/boot/vmlinuz-4.15.0-9-generic root=UUID=707d0f89-4b1d-4432-9d50-6058dc4c1ee9 ro rootflags=subvol=@ quiet splash vt.handoff=1 RelatedPackageVersions: linux-restricted-modules-4.15.0-9-generic N/A linux-backports-modules-4.15.0-9-generic N/A linux-firmware 1.170 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/15/2013 dmi.bios.vendor: Phoenix Technologies Ltd. dmi.bios.version: P14AAJ dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: SAMSUNG_NP1234567890 dmi.board.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.board.version: FAB1 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.chassis.version: 0.1 dmi.modalias: dmi:bvnPhoenixTechnologiesLtd.:bvrP14AAJ:bd04/15/2013:svnSAMSUNGELECTRONICSCO.,LTD.:pn530U3C/530U4C:pvr0.1:rvnSAMSUNGELECTRONICSCO.,LTD.:rnSAMSUNG_NP1234567890:rvrFAB1:cvnSAMSUNGELECTRONICSCO.,LTD.:ct9:cvr0.1: dmi.product.family: ChiefRiver System dmi.product.name: 530U3C/530U4C dmi.product.version: 0.1 dmi.sys.vendor: SAMSUNG ELECTRONICS CO., LTD.
