dmesg output

I am using an old Chromebook that I have flashed with a Coreboot image.

Installed FreeBSD 14.0 RELEASE on it with drm-kmod and Gnome.  The keyboard
works fine.  The trackpad does not respond at all.

Found the following in dmesg output:

driver bug: Unable to set devclass (class: ppc devname: (unknown))
