5.2.1 Install fails probing harddrive

I'm trying to install 5.2.1 on a Cappucino PC 
(http://www.cappuccinopc.com/cappuccinotx3.asp) and getting the 
following when booting from the 5.2.1 install cd. It hangs while 
identifying the harddrive. The following is a snip from a verbose boot, 
i've also tried booting with ACPI disabled just to rule that out. Safe 
boot does the same thing.

Now the weird part, i tried booting from a 5.1 Release CD and it was 
able to get to the installer. I could always install 5.1 and cvsup to 
5.2.1/ current but it may be a waste of time.


thanks
