I too have had the same issue...
Notebook: Dell XPS 13 9360 bios: tested with 2.9.1 and 2.10.0 OS: Debian stretch 9.8 Kernel: 4.9.0-8 debian 4.9.144-3 Wi-Fi/BT module: Intel Dual Band wirelss AC 8265, rev=0x230 Firmware: iwlwifi-8265-22.ucode BlueZ: 5.43-2+deb9u1 BT Mouse: Logitech MX anywhere 2s ------ When attempting to pair one of 4 things will happen: 1. the bluetooth module locks up and stops responding - time out messages are seen in dmesg 2. The wifi will reset but will return to a normal state with a failed bluetooth as above 3. wifi and bluetooth will disappear and stop responding but wifi is recoverable by invoking rfkill via the wifi hot key ( fn f12 ) 4. The entire device stops responding and shortly after the machine will freeze - there may be a panic but i can't see it due to lock up ( nothing written to logs ) The pairing process will not complete as the device stops responding before then. Resetting the pci device via the /sys interface results in an instant hang Other two xps devices i have contain ath10k cards and dont seem affected, mouse can also be paired to an android device without issue. tried bios upgrade to no avail. attempted using firmware direct from linux-firmware repsitory instead of firmware-iwlwifi package ( 20161130-4 ) no change only fix i've found for this was to add the bt_coex_active=0 option when loading the module ( modprobe: options iwlwifi bt_coex_active=0 ) this allows a connection to occur and for the device to pair however the mouse movement on screen seems to be quite jittery at times. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773897 Title: [regression] Logitech M337 mice are automatically disconnected after connected To manage notifications about this bug go to: https://bugs.launchpad.net/bluez/+bug/1773897/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
