>Description:
I was trying to install NetBSD 2.0.2, 2.1 or 3.0 on my Amiga 3000,
but the miniroot crashes when booting off swap. At first, I suspected
hardware problems, but it turns out that the NetBSD 1.6 miniroot
installation works just fine. I also have a fully working NetBSD 1.6.2
installation on this machine, running off a different HD.

Here is what I posted to port-amiga:

>How-To-Repeat:
Prepare miniroot installation as per documentation, boot miniroot
off swap.
