I have successful installed 14.0-CURRENT on the lenovo x1 carbon g8, but
it just hangs when I tried to build the kernel. And I'm unable to enter
the debugger. I think it happens when CPU load reaches some level.

I tried to disable hwpstate_intel via loader.conf and it helps:

% grep hint /boot/loader.conf
hint.hwpstate_intel.0.disabled="1"

My old lenovo x1 carbon gen 4 was hanging on boot with the same symptoms.
