Same Hardware, same bug.
I remember this used to work in the past, but I didn't use Bluethooth
for about a year. (on an ASRock X570 Taichi)
$ uname -a
Linux workstation 6.5.0-17-generic #17~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue
Jan 16 14:32:32 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
$ lspci -k -s 05:00.0
05:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)
Subsystem: Intel Corporation Wi-Fi 6 AX200NGW
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
That mentioned workaround works for me as well:
$ sudo rmmod btusb
$ sudo modprobe btusb
While trying to fix this myself, I found that the following steps made
Bluetooth available again without (cold) power cycling:
1. reboot into EFI
2. disable Bluetooth
3. boot to OS (Linux Mint 21.2)
4. reboot into EFI
5. enable Bluetooth
6. boot to OS
Maybe this helps to get more ideas, what's going on.
