You can test evdev directly w/o Xserver started by running of
evemu-record utility from
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218383 PR to see if
events are matching  keys or not.
Note: depending on kern.evdev.rcpt_mask sysctl value only one of kdbmux
or AT keyboard devices should emit events. Not bother!

This lines are not required usually if you are using devd or udev
autoconfiguration backends. Moreover they can do a harm.
Could you compare input device lists from xinput command output with
evemu-record output?
They should be the same except "Virtual core XTEST" entries. If they are
not, that could be the culprit. It is possinle that
Xorg receives one key event several times. In that case try to uninstall
xf86-input-keyboard and restart Xserver than.

Try run evemu-record on synaptics device node to see if you are
receiving events from touchpad during freezes or not
