Since Kernel 6.11 compiled from vanilla source, I get occasionnaly an Oops at
boot on my Lenovo Slim 5.
This is a regression.

Kernel 6.11 / Slackware 64 (Slackware 15 + recent Mesa).
AMD 7840HS 16Go
When the problem occurs, the boot doesn't finish, but I got the following in
syslog:

Christian, I consider forwarding this by mail to the developers. Can I CC you
when doing so? This would expose your email address to the public.

Also: I guess bisecting
(https://docs.kernel.org/next/admin-guide/bug-bisect.html ) is not an option
given the "occasionally" aspect?

Hello
Yes you can forward and Cc me.
The problem is effectively rare (got it twice only for now).

I also see this occasionally on boot on my Framework 13 laptop running Linux
6.12.3. The result is a hang after the GDM login screen and the user session
doesn't start. I think it also happened on 6.12.1.

I didn't managed to apply the patch on 6.12.6.
There was rejects I fixed manually, but it doesn't build with the following 
error:
drivers/bluetooth/btusb.c: Dans la fonction « btusb_probe »:
drivers/bluetooth/btusb.c:3862:21: erreur: « struct btusb_data » n'a pas de 
membre nommé « disconnect »
 3862 |                 data->disconnect = btusb_mtk_disconnect;

The commit doesn't contains header diff.

FWIW, `btusb.enable_autosuspend=0` seems like an acceptable workaround for now.
