Ok, I have tried it with all the other patches also applied. Maybe I should
try with only this one? I see you are pulling all your changes into
RELENG_5, so maybe I should try with just that and no patches?

Anyway I have booted twice now and both times it booted, but in degraded
mode. It looks like this:

How can I see why it starts in degraded mode or can one deduce it from
the above output?
