As I suspected, the error: Bluetooth: hci0: last event is not cmd complete (0x0f)
is itself not a bug. The only bug is that the error was displayed when it shouldn't be. So if you have any actual Bluetooth bugs then they should probably be logged elsewhere. That is according to https://bugzilla.kernel.org/show_bug.cgi?id=198699#c24 It appears the "fix" to stop the error message appearing is in the mainline kernel 5.0 (AKA version 4.21) onward. But again if you have any problems with the behaviour of Bluetooth then please open a new bug. ** Changed in: linux (Ubuntu) Importance: Medium => Low -- 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.
