Title:
6.14.0-28-generic kernel update broke network and touchpad
Status in linux-hwe-6.14 package in Ubuntu:
Triaged
Bug description:
Recent kernel update to `6.14.0-28-generic` for Ubuntu 24.04 on my Thinkpad
P14s Gen5 broke networking, touchpad and thunderbolt functionality. The system
does not see any wi-fi network interfaces in settings.
Touchpad - only buttons work, tapping on a pad does nothing.
I rolled back to `6.14.0-27-generic`, everything works fine there.
