Same here on a ThinkPad Carbon X1 gen 7:

sysctl hw.model
hw.model: Intel(R) Core(TM) i7-8665U CPU @ 1.90GHz

My previous and okay BE was running 308d3d6be6da stable/13 and I've tried rebuilding using several newer commits all ending
with a kernel panic due to not being able to load i915kms (fatal trap 9:
general protection fault while in kernel mode).

I then decided to mount 1 of those newer BEs (based off of commit
50f61166f7b9) and remove i915kms from
kld_list and boot into that BE.
System came up, then reinstalled latest drm-510-kmod from ports,
kldloaded i915kms and then re-added i915kms to kld_list

[/usr/src] uname -aKU
FreeBSD harbinger.fritz.box 13.1-STABLE FreeBSD 13.1-STABLE #0 n253282-50f61166f7b9: Fri Jan  6 13:09:11 UTC 2023     root@harbinger.fritz.box:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 1301510 1301510

I'm now rebuilding world using the latest commit 1149f0ec2b18 to see
what happens and if I need to perform this dance again or not.
