I’m running 13 -STABLE from 10 days ago on a Thinkpad Yoga 3rd gen, and
hwpstate_intel works fine, never had a problem.

Thanks for the feed back. Good to know most people won't encounter the
problem. Perhaps it is a bios issue specific to the model. I did update
to the latest bios version but that made no difference.

I have chosen to rollback to 12.2 as it works perfectly for me.




Cheers, Fred



There are two long tickets about this. Take a look at tickets 248659
 and 253288
. This problem
appeared in 13-current in Jan 2020 and I first saw it on my new Lenovo L15
that summer. It appears specific to Lenovo laptops. It appears that similar
issues have been seen with Linux.


Thank for the links to the bug reports, it would appear to be the same 
issue. I tested my wife's X1 Carbon Gen 3 and it worked fine. Perhaps a 
bios bug with the processor in my 4th gen.


CPU: Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz (2808.11-MHz K8-class CPU)

In the 24 hours I tested 13.0, I also had some X windows failures while 
waking up from suspend which never happens with 12.2. Oh well, no worries.

ThinkPad X1 Carbon Gen 4 unable to boot 13.0-RC1

2021-03-19 Thread Fred Hall via freebsd-stable 
I have a ThinkPad X1 Carbon Gen 4 (20FCS0NB00) which has happily run FreeBSD 11 
and 12, but which can't boot 13.0-RC1 from memstick or via freebsd-update. In 
both cases the boot process locks up on the line "hwpstate_intel0:  on cpu0"
If running freebsd-update, a work around is to add 
hint.hwpstate_intel.0.disabled="1" in loader.conf. See the note under the
