Page fault during 15.1 update

I'm in the process of upgrading from 15.0 to 15.1 and have just done a reboot after running

freebsd-update -r 15.1-RELEASE upgrade

and am greeted with

trap number = 12

panic: page fault

What to do?

That didn't change anything. I suspect you did freebsd-update install, then rebooted.

Boot to single user mode, disable kld_list in rc.conf. Reboot and continue with the upgrade.

Your DRM driver is the one that's crashing the system, it was built for 15.0 and now gets loaded on a 15.1 kernel.
 
hm, I am having this on my 15.0 for quite some time, however, have always procrastinated research and root cause analysis.
