            Bug ID: 298871
           Summary: Touchpad on Lenovo T14 AMD only recognized after
                    second boot
           Product: Base System
           Version: 15.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: spaceodyssey@gmx.de

After a cold boot the touchpad is not recognized.
However a direct reboot always fixed that so far and the touchpad was working
after a warm boot (on roughly 20 boots now).

I debugged it to some extend together with Claude. I did not find a way to fix
the issue on a cold/bad boot and have to resort to the restart to get touchpad
working.

It is fairly good reproducible on my T14. If somebody points me into the right
direction I can gladly provide detailed logs for a 'good' and a 'bad' boot to
debug this further.
