Ok, you didn't actually read my log output and assume things. The log message disappears completely WHEN my Bluetooth starts working. The actual opposite of your argument. I.e., the message only appears when my machine is "unhealthy". The message does not occur concurrently at all.
Regardless, I can redo my test say 3 times before/after suspend/reboot/logout and if the same pattern occurs it is not a coincident for sure. The message will then be related to the issues (already) reported in several other bug reports. The coder behind this message is arguing, from what i can surmise, that this is an error that is not handled, not that it is a superfluous debug statement as seen in statements above: https://www.spinics.net/lists /linux-bluetooth/msg75270.html -- 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 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.
