Title:
Bluetooth Broken In Kernel Versions 6.5+ (Realtek)
Status in linux package in Ubuntu:
New
Bug description:
Starting with kernel 6.5 the external Bluetooth USB dongle based on
Realtek stop working.
This issue occurs on either UBuntu 22.04, 23.10 and 24.04 when kernel
version is > 6.5. On a lower kernel version it works as we were using
it for almost 2 years without issues.
Version signature: Ubuntu 6.8.0-22.22-generic 6.8.1
USB bluetooth device: Bus 001 Device 003: ID 0bda:a729 Realtek Semiconductor

I have installed BlueZ package https://www.bluez.org/ and trying to
discover the device which worked but i am always getting errors when
trying to connect to the device via BT (after pairing)
