Subject: Built-in Intel Bluetooth device disappeared after booting Linux 6.7
Precedence: bulk
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

I am running an alder lake i7 1260P with built-in bluetooth.
This adapter always worked fine with no special config, but since I booted =
Linux 6.7, the device completely disappeared. There's no mention of bluetoo=
th in the kernel or system logs, there's no device node, and there's no ent=
ry in lspci.
When I boot the last working kernel again (6.6.10), the device also doesn't=
 appear (even though it did before, see logs below).

I also tried booting a ubuntu live ISO to exclude any configuration issues =
with my distro's (NixOS) kernel or such, and also there the device did not =
show up.

I am not sure at all that this is related to the kernel, but I wouldn't kno=
w where else to look. I am including below my system logs (journalctl -g 'b=
lue|Blue|Linux') showing the kernel version and the bluetooth related entri=
es. As you can see, on 6.6.10 the bluetooth module got loaded, /dev/hci0 ge=
ts created, and user space sets up the bluetooth stack.

The next boot entry is the first time I booted 6.7, and there's no mention =
of bluetooth at all in the logs. I tried to load the bluetooth module manua=
lly, which succeeds but doesn't create a device node.

When I boot 6.6.10 again now, I get exactly the same as on 6.7. I don't kno=
w if the kernel could have done anything persistent to the device that make=
s that it doesn't get initialised anymore?

I'm not sure how to debug this further, let me know if there's a way to get=
 more detailed info in the kernel logs or such.

Thanks,
Ramses
