Tried to install from both 8.0-BETA{3, 4}-i386-dvd1.iso on a Phenom 9600
system and having
some disk problems.

The system is running 6.x and/or 7.2 FreeBSD (on different drives).

Disconnected rest drives and only left 7.2 drive in.
ad0: 76319MB <Seagate ST3802110A 3.AAJ> at ata0-master UDMA100

Boot 8.0-BETA3-i386-dvd1.iso and sees no partition at all on the 7.2 disk.
Boot back to 7.2 and everything works fine, so system has no hardware

Boot 8.0-BETA3-i386-dvd1.iso again, still sees no partition, so
reconfigured partition with
autoconfigure - A

512M for / on /dev/ad0s1a
about 4G for swap on /dev/ad0s1b
about 2.2G on /var
512M for /tmp
rest spaces are for /usr

After commit, installation says --

Unable to find device node for /dev/ad0s1b in /dev
The Creation of file system will abort.
[Press enter or space]

Hit CR and see some other errors, then back to installation menu.
Reboot the system, 7.2 is gone.

Download 8.0-BETA4-i386-dvd1.iso and burned another DVD, also did verify
between DVD and ISO for OK.
Run installation from Beta4 DVD, the same problem presents again.

If my memory is correct, either 8.0-Beta1 or one version earlier than it
was working on this machine.

Is anything changed that requires different installation procedure? or
is this a bug introduced recently?
