--- Comment #40 from Jonathan Vasquez <jon@xyinn.org> ---
This crash/lock up also happens on my Thinkpad X260 on FreeBSD 13.1-RELEASE
amd64. If I close the lid on AC power, everything works fine. If I close the
lid on battery power, the system immediately locks up when I close it.

Adding "hint.hwpstate_intel.0.disabled=1" to /boot/loader.conf was the only
thing that "fixed" it.
