@ltning:

If you have a gen8 I'd be very interested in knowing how it works for you. Mine hard-wedges under load after a minute or two (no X running, just building pkg immediately after install), and at random intervals if idle. I did get drm-devel-kmod working and after many many reboots plasma5 runs (for a short while). Basically nothing else works.

I am assuming you are running CURRENT. My gen7 started hard-wedging (first only under heavy load, later just "a minute or two after startup") too. It seems like someone was fiddling with CPU powersaving sometime around February and messed up for these CPUs. I have not had time to bisect for the exact commit, it would be great if someone could. In the meantime, my (sad) workaround is to disable all CPU powersaving:

/boot/loader.conf

hint.hwpstate_intel.0.disabled="1"

Any news regarding this issue? I upgraded my Thinkpad X1 Carbon to
FreeBSD 13.0-RELEASE and experience the same issue. I have applied
the suggested workaround for now. Do you know if this issue has been
reported as a bug?
