Installting FreeBSD on and old Thinkpad X31

[Gordon Bergling]

Hi,

I recently got and old Thinkpad X31 on which I would like to install
FreeBSD on it. I tried to boot 13.0-RELEASE and 12.2-RELEASE, but the
boot stops with "Root mount waiting for: usbus0 usbus1 usbus2 usbus3 cbb0 cbb1 CAM"

I tried to boot without ACPI and in SAFE mode, but had no luck with these options.

Has anyone a hint, how to install and properly boot FreeBSD on this old laptop?
