I get a similar screen - so yes I'd say it's stopping at the same

I'm doing an initial install - on the first machine I have to run
dragonflybsd so don't have an environment on which I could rebuild the

similar, put dragonflybsd in a VM and then use that to rebuild the
kernel in the install media?
