Public bug reported:
I'm running ubuntu 24.04 on a Dell XPS laptop
kernel 6.8.0-45 works well
When upgraded to 6.8.0-55 - there is seemingly no proper usb support
(external devices don't work), no external monitor available, bluetooth
is absent and touchpad works in a very basic mode.
I'm not sure what is relevant to diagnose this problem.
