Public bug reported: Same problem exactly as encountered with Intel 9560 is also happening with Intel 9260.
Update to linux-firmware 1.173.8 did not fix the problem. Everything is working fine when using 4.15 kernel, but not for 4.18+ 5.0+. Reference problem: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1829737 You-Sheng Yang advised to do this by email and it fixed my issue, so I think the 9260 driver would need to be updated in the bionic branch (it seems to be updated in newer branches). -- Basically you should try copy the latest firmware (ibt-*) under https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/intel , power off the device completely and power on, then have a check on bluetooth pairing. -- Linux ideapad 5.0.0-20-generic #21~18.04.1-Ubuntu SMP Thu Jun 27 04:04:37 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux OS: Linux Mint 19.1 Tessa x86_64 Host: 81JB Lenovo ideapad 730S-13IWL Wifi/Bluetooth card is Intel 9260 xxxx@xxxx:/etc$ dmesg | egrep -i 'blue|firm' [ 0.099619] Spectre V2 : Enabling Restricted Speculation for firmware calls [ 0.173124] ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored [ 2.379392] [Firmware Bug]: Invalid critical threshold (0) [ 2.699758] [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4) [ 6.259427] iwlwifi 0000:73:00.0: loaded firmware version 43.95eb4e97.0 op_mode iwlmvm [ 6.337749] Bluetooth: Core ver 2.22 [ 6.337767] Bluetooth: HCI device and connection manager initialized [ 6.337770] Bluetooth: HCI socket layer initialized [ 6.337773] Bluetooth: L2CAP socket layer initialized [ 6.337777] Bluetooth: SCO socket layer initialized [ 6.368073] Bluetooth: hci0: Firmware revision 0.1 build 201 week 49 2017 [ 7.309936] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 7.309938] Bluetooth: BNEP filters: protocol multicast [ 7.309943] Bluetooth: BNEP socket layer initialized [ 17.197268] Bluetooth: RFCOMM TTY layer initialized [ 17.197275] Bluetooth: RFCOMM socket layer initialized [ 17.197284] Bluetooth: RFCOMM ver 1.11 [ 104.453159] Bluetooth: hci0: request failed to create LE connection: status 0x0c [ 104.509148] Bluetooth: hci0: request failed to create LE connection: status 0x0c [ 104.551340] Bluetooth: hci0: request failed to create LE connection: status 0x0c [ 104.589338] Bluetooth: hci0: request failed to create LE connection: status 0x0c [ 104.623323] Bluetooth: hci0: request failed to create LE connection: status 0x0c ** Affects: linux-firmware (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1835449 Title: Bluetooth: hci0: request failed to create LE connection: status 0x0c (Intel 9260) Status in linux-firmware package in Ubuntu: New Bug description: Same problem exactly as encountered with Intel 9560 is also happening with Intel 9260.
