The "last event is not cmd complete" is in most/all cases a red herring, so please don't focus on that. There's a patch in mainline that will remove it for all valid situations (i.e. when the command completed with command status instead of command complete): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1629db9c75342325868243d6bca5853017d91cf8
It seems like this issue has probably lots of different bugs mixed into it, all incorrectly attributing themselves to this misleading warning message, when in fact there's something unrelated going wrong. Those that are experiencing issues even after applying the patch I referred to, please open new issues, especially if the "last event is not cmd complete" message goes away for you with the patch. This one can probably be closed since the misleading message should now be gone. -- 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.
