I can confirm this issue exists on both Ubuntu 22.04.3 and 24.04.beta (2024-01-25) with Linux 6.5x.
Both the Logitech (Bluetooth) M535 mouse and Microsoft Surface (Pro 7) Type Cover were problematic with Linux 6.5x to the point where they were unusable (timeouts or non-responsive for the mouse and boot-up or non- responsive Type Cover). The only solution I found was to re-image with Ubuntu 22.04 (offline), place a hold on the installed Linux 6.2x, then connect to internet to complete the installation and updating process. The Linux hold prevents the updating to the 6.5x kernel. If Linux 6.5x got installed (usually as a choice to have internet connected during the OS installation which followed with an update/upgrade), it had to be removed and replaced by Linux 6.2x to resolve the Bluetooth issues with the mouse and Type Cover. Bluetooth failed to perform properly on Ubuntu 24.04 or 22.04 with Linux 6.5.0-14-generic. Bluetooth performs properly under the following conditions: Ubuntu 22.04.3, Linux 6.2.0-26-generic (hold), gnome-bluetooth 3.34.5-8, bluez 5.64 lsusb - Bus 003 includes three devices: Device 004: ID 045e:09c0 Microsoft Corp. Surface Type Cover Device 003: ID 8087:0026 Intel Corp. AX201 Bluetooth (Logitech M535 mouse) Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub I don't have any additional specifics for the Linux 6.5x builds of Ubuntu 22.04 and 24.04 other than I was unable to get the Bluetooth mouse and Type Cover to work properly. I went through several builds of both Ubuntu versions and the only one that worked properly was the one I detailed above. -- 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/2051720 Title: Bluetooth Broken In Kernel Versions 6.5+ (Intel AX210) Status in Linux: Confirmed Status in linux package in Ubuntu: New Bug description: ``` kernel: Bluetooth: hci0: command 0xfc05 tx timeout ``` This issue started with kernel 6.5.
