            Bug ID: 249987
           Summary: Lenovo X120e touchpad failing
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: jwb at freebsd.org

Since a few months ago, /dev/psm0 sometimes does not get created on boot and
sometimes disappears after boot, often after a suspend/resume cycle.  The only
workaround I've found is to power off the machine and restart, which brings
back touchpad functionality only sometimes.

I did  fresh 12.2-BETA3 install before filing a PR to see if the issue may have
been resolved, but it has not and in fact a new issue has appeared: Tapping no
longer works as a left-button click.

I've added hw.psm.mux_disabled=1 per syslog suggestion and will report back
after a testing period once I know if it helped.

Data from 12-2-BETA3:

dmesg:
