I have a ThinkPad X1 Carbon Gen 4 (20FCS0NB00) which has happily run FreeBS= D 11 and 12, but which can't boot 13.0-RC1 from memstick or via freebsd-upd= ate. In both cases the boot process locks up on the line "hwpstate_intel0: = <Intel Speed Shift> on cpu0" If running=C2=A0freebsd-update, a work around is to add hint.hwpstate_intel= .0.disabled=3D"1" in loader.conf. See the note under the Eighth Generation = (2020) in https://wiki.freebsd.org/Laptops/Thinkpad_X1_Carbon I was quite surprised to find the lack of support for hwpstate_intel in 13 = when it apparently worked under 11 and 12. Does anyone know the status of h= wpstate_intel on ThinkPads? Cheers,=20 Fred
