--- Comment #30 from Ulrich Spörlein <uqs at FreeBSD.org> ---
I'm not sure what is worse, removing P-states from every non-Thinkpad owner, or
having a release out there that fails to boot on Thinkpads (which are probably
the most often used laptops with FreeBSD, maybe??)

Can we quirk/block the P-State support and disable it whenever the
ACPI/BIOS/Firmware/whatever is from Lenovo (and/or the model matches
"Thinkpad")?

That would allow it working out of the box (but is too late for 13.0-RELEASE).
