>Organization:
Evolutionary Software Systems
>Environment:
Microsoft Virtual PC 2007 on a XP Pro host
>Description:
I can't boot from CD (ISO image) to install 6.3 on a new virtual machine.
I hang with a message:

 Trying to mount root from ufs:/dev/md0

I've tried both the disk1 image and the bootonly image.
These are the latest images downloaded last night, with no modifications.

Researching with google, I see that some have had this problem in the past,
but I had not seen it with 6.0 or 6.2.  

How do I proceed?

>How-To-Repeat:
It's completely repeatable, following the handbook instructions on building
a virtual guest using Microsoft Virtual PC.
>Fix:
unknown

State-Changed-Why:  
How long does the machine hang for?  Have you tried waiting say 10 
minutes?  I suspect you are seeing the same problem as is in  
PR kern/91476.  Can you try disabling the floppy controller from the 
loader with 
set hint.fdc.0.disabled="1" 
and seeing if that makes any difference?

 Sorry, I haven't had a chance yet - I ran out of disk space aand haven't
 had time to move enough stuff around to make room for a virtual machine.
 
 If you want to have a go yourself, possibly the easiest thing to do will
 be to install 6.2 onto the machine, and try to establish when the
 breakage began.  With the following cvsup file:
 
 --------------------------------------
 *default host=cvsup3.freebsd.org
 *default base=/usr
 *default prefix=/usr
 *default release=cvs tag=RELENG_6
 *default delete use-rel-suffix
 *default date=2007.04.01.00.40.00
 src-all
 -------------------------------------
 
 update your source, recompile the kernel, and see if the new one boots.
 If it does, go forward another four months and see if that one boots,
 etc.  If not, go back a month or two.  Within a small number of
 recompiles, you'll probably be able to narrow the change that breaks
 things for you.  Depending on how much effort you want to put in, you
 should be able to narrow it down to a particular 10 minute or so window
 - and have a list of the commits in that time to look at.  This is
 basically what I was planning on doing.
 
 Out of interest, once hung, does capslock still work on the keyboard?
 If so, you could also try compiling ddb into the kernel and when the
 machine hangs, press ctrl-alt-escape to drop to the debugger.  Athough,
 I'm pretty sure when I recreated the issue, the keyboard was
 unresponsive.

 So I can keep track of things:
   2007.07.12.00.00.00 boots fine
   2007.09.12.00.00.00 boots fine
   2007.11.01.00.00.00 boots fine
   2007.12.01.00.00.00
