Package: firmware-iwlwifi
Version: 20210818-1
Severity: important

Dear Maintainer,

   * What led up to the situation?
Kernel upgrade from 5.14.0-4 to 5.15.0-1

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Open the Bluetooth window in Gnome preferences to pair my laptop with
an external device. 

Also, enter `show` in bluetoothctl prompt.

   * What was the outcome of this action?
In Gnome preferences, it is written (in French) "Pas de réseau
Bluetooth trouvé", which translates as "No detected Bluetooth network"
(I guess).

In bluetoothctl, `show` returns No default controller available.

   * What outcome did you expect instead?
Before the kernel upgrade Bluetooth was working fine. My laptop has an
Intel AX200 wireless controller that requires firmware-iwlwifi. Wifi
is still functionning as usual.
If I reboot and select in Grub the previous kernel 5.14.0-4, Bluetooth
is working again.
