8.0 hangs at boot time Thinkpad x32

[André]

Hi there,

try to install 8.0-R on TP X32 with a 250GB WD HDD (WDC WD2500BEVE-00WZT0
250G)
from an external USB cdrom.

After probing ad0 it recognizes ad0 but then it freezes with HDD LED
burning.

OK, ACPI disabled, short time after entering the Standard procedure it
freezes.

Same problem with 7.2-R

Under OpenBSD it works without any probs.

Any Suggestions? 

TIA

André
