Someone mentioned the same boot hangup problems I've had and the 'fix'
was to boot to some other OS first, like Linux. I tried Slackware 12.1
(also hangs somewhere during boot) and then Ubuntu 8.04 (am able to go
into the install screen) but rebooting back to freebsd is no go. Then
I recalled we were able to successfully install 64-bit Windows 2003
Server on it. So I booted it to the windows 2003 server just to the
point where it asks to install it, then rebooted it to the already
installed FreeBSD.

I have also an output of acpidump but its quite huge, pastebin has limits:

Email me privately if you want this (or I can give this to someone w/
ample bandwidth and a web server).

Also it detects only 16CPUs instead of 24. Win2k3 detects all 24.

But I have an HP DL380 Quad-Core Xeon that rebuilds the world in just
13 minutes :-p

Thanks.
