regression on releng_7 (and 8 beta1 vs proliant dl 385)

[Raul]

Hello,

I've tried an 8 beta 1 (from usb image, and source upgrade) and releng_7 
(both amd64) from today on a hp's proliant 385 with the same 
misbehaviors, kernel hung during boot at exactly the same point. Last 
message on the console is: 'pci0: <ACPI PCI bus> on pcib0' and the disk 
led activity is solid on. After some trial / error and looking for more 
information, I've tried verbose boot and surprisingly the machines 
finish the boot process flawlessly and ask for credentials.

verbose dmesg availables at:

Both boxes used to run releng_7_2 perfectly, and are ready to try 
whatever you ask me ;).

Thanks a lot in advance.

Regards,
Raul.
