Bug description:
>>> Copied from an email to kernel maintainers sent on 31.10.2023
15:23:52
Moving from Ubuntu 23.04 to 23.10 came alongside a kernel update from
6.2.0-36-generic to 6.5.0-10-generic. As of the update, plugging in
my USB-C monitor causes my machine to immediately shut off its native
screen, followed by a crash and reboot.
My machine is a Lenovo Yoga C940-14IIL with an Intel i7-1065G7. No
logs are written to /var/log/syslog or journalctl. I have been able to
use my screens normally by reverting to the old kernel. This is my
first time reporting an issue to the regressions mailing list,
hopefully this provides sufficient detail. Thank you for your work.
