Title:
Bluetooth Broken In Kernel Versions 6.5+ (Realtek)
Status in linux package in Ubuntu:
Incomplete
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.
