13.0-RC5 crash/reboot on cold-start, how do I get a textdump ?

[Kurt Jaeger]

Hi!

I have a new laptop (Lenovo P14s), installed freebsd 13.0-RC5 on it
with ZFS, geli encryption.

If I cold-start the laptop, the first boot will crash before
going multi-user and reboot, and the next boot will be fine.

I activated /var/log/kern for kern.*, but the crash happens
so early that nothing is logged.

How can I get a textdump of that crash ?

Would boot_ddb="YES" in /boot/loader.conf help ?
