Bluetooth doesn't work after last system upgrade

Hi all,

it's my first post here, so be nice :-). I have a fresh installation, made following the guides in Arch Wiki and after circa 10 hours of work I have Arch with internet connection, X, lxde, sound and a lot of features working perfectly. But today...

I've done last complete upgrade with "pacman -Syu" about an hour ago. I noticed a new kernel installed. After a reboot, all works fine, except for bluetooth, that works well since the uggrade.

1 - The bluetooth module wasn't loaded, so I made it working with a "modprobe btusb". I havent't understand how to reload that module automatically anytime I reboot, but this is another question, I read the wiki to resolve it.
2 - Also after loading modules, bluetooth wasn't active (bluetoothctl doesn't start). So i start it via "systemctl start bluetooth.service".
3 - After that, bluetoothctl apparently works, but if I do "list" to set my controller when in bluetoothctl, nothing happens. No response, neither errors nor other messages.

My pc is a HP Spectre laptop; Arch is installed on an external SSD disk. All commands are execute from a lxde console with "su root".

I'm blocked, because now apparently bluetooth  is on, but I can't see the controller of my laptop, and I don't know how to do.

Thanks to all for helping me,

Franco

There is a bluetooth issue with some intel BT controllers. See here

So I have to wait next kernel release in Arch or build my own compiling it with the patch... I think i'll wait.

Re: Bluetooth doesn't work after last system upgrade

Today's update to 5.15.4 in official repos didn't fix it for me on Intel AC 3165.
Cold booting into Arch - BT works alright in Gnome.
Restarting into Arch - BT doesn't work in Gnome.
Putting the laptop to sleep and then waking it up again makes BT work fine even if it wasn't.
