5.3 BETA 5 and 6 won't start install with ACPI enabled

[Johan Hendriks]

Hello all 
 
I have a Intel Motherboard with a Intel Celron 1.2 Ghz Proc type
D815EGEW
 
When I try to install the BETA 5 and ^on this machine it stops and need
a power cycle to reboot.
 
It will boot when I disable ACPI
 
The last two line's on my Monitor are
 
ATAPI_RESET time = 70us
ACD0: CDROM <CRD-8400B/1.00> at atea1-master PIO4
 
Then nothing and needs power cycle
