I have seen the same thing. What I found is that you need to replace your disk
image with a fresh one every time you try a fresh install. My guess is that the
emulated controller is writing garbage to the drive, then the installer the
next time through is reading this and thinking that the garbage is valid memory
locations and is getting confused. I've been using the 'Upgrade' option to
debug the error below to avoid having to do this every run through.

I'm looking into this now. I've tossed a basic implementation together, but the
error messages continue to flood onto the installer's screen. It appears to be
getting interrupts that it isn't expecting. After going through the debug log
it looks like the installer pokes a bunch of LUNs and I think that it may not
want interrupts for the LUNs that don't have a drive attached to them. This is
just a guess though. I've got more testing to do.
At this point I'm not sure if this error has anything to do with the failure of
installation. I hate error messages like this though (which wouldn't be there
if we emulated correctly), so I'm going to try and fix this first and go from
there.
