I have been seeing this happen intermittently on both a VAX and an
i386 system recently. Sometimes it hangs immediately, sometimes just
after "Syncing disks..." sometimes after "Syncing disks...done".
Sometimes it makes it all the way.
I was seeing this a lot on the VAX over the past 2 weeks or so, and
suspected it was a port-specific problem. It hasn't happened much (or
maybe at all? I'm not sure) since I stopped netbooting the machine
and started booting it from local disk.
The i386 machine where I just started seeing this problem (after
upgrading to -current from 8/30) is a diskless machine.

I just upgraded my boot blocks on the server. My guess is that you
couldn't open the raw partition because your system was at securelevel
1. Try it from single-user mode. I was able to installboot from
multi-user mode but I have "options INSECURE" in my kernel config.
entropy -- it's not just a good idea, it's the second law.
