Lo! Just booted 6.9 for the first time and noticed the Bluetooth code
causes an Oops (see below) during boot that did not happen with 6.8 and
earlier. This is on Fedora 40 with a vanilla kernel on a Lenovo Thinkpad
T14s Gen1 AMD.
Do I need to bisect this? Or is this known already? Or does anyone by
chance an idea what might cause this? Or is there some other way to get
down to the problem?
Ciao, Thorsten
