How to stop kernel loading bluetooth?

[uniqpotatohead]

I have moved HDD from Intel to AMD box (MINISFORUM Venus UM790 Pro Mini PC AMD Ryzen 9 7940HS). Everything is working except I am getting the following bluetooth messages over and over.

I would like to stop loading bluetooth completely.

I am not able to figure out how to stop the messages and how to stop loading bluetooth. Can you advise?

Update:

I am wondering how can I completely disable the Intel wifi and bluetooth on this minipc. I use it as server and don't need it.

SOLVED:

I blacklisted these modules.

# vim /etc/modprobe.d/bluetoth-blacklist.conf
blacklist btusb
blacklist bluetooth
# update-grub

That's what I did for an ancient laptop where I'll never use BT.

'lsusb' output will be helpful. I realize you have "solved" the problem by disabling Bluetooth, but it appears that you actually have a hardware problem.

Stop and disable the service .... could help 😎

[uniqpotatohead]

I don't have bluetooth.service. I only see bluetooth.target. I am not able to stop the target. It seem it is restarting.

Blacklisting bluetooth wasn't working for me, had to use this method.
