I see the same thing using your script. A few observations:

1. We've seen this message before (usually on APUs), but only a single time (eg,
just one of the signal lines gets displayed). And IIRC it was a different signal.

2. In your case, the stream of messages seems to stop after some time and boot
proceeds normally after that.

3. When I built the image using your script, on the second boot, I saw no
messages.

I'm not sure what's causing the problem, can you try with 6.3 release? (I'm
assuming you are using -current here? that's what I tested also)

Also some more notes:

4. in my test the default install location came up as http, so your script's
pressing of "enter" for install path hung. I had to change the default location
in the script to be cd.

5. Your customization step at the end should probably fixup /etc/ttys or
you won't be able to log in to the machine via serial (since no getty will
be spawned there). I sat there waiting for a while in qemu only to realize
the getty was waiting on the vga console, not serial. YMMV.
