Problems with Nacona Xeons

Hey Guys,

I have a Dual Xeon (With EM64T) system running FreeBSD 5.4 AMD64 - Release
(with a -stable kernel). I can't get the kernel to see my second CPU. I have
recompiled and retuned and done everything I could to get it to see the
second CPU. The guys on IRC (##Freebsd on freenode) told me to post this to
this list.

I do have the ACPI disabled as it doesn't work right yet. The Motherboard is
a Tyan S5350 ( ) running with
2 Dual Nacona Core Xeons. I had the datacenter check the BIOS and everything
is as it should be. I have Registered ECC RAM on it as well.

Both CPU's were recogized by Centos 4.1 X86-64, however I prefer FBSD to
anything Linux. So if you guys could help me out I would appreciate it. I
think I have given you all the relevant information I Hope but if not just
ask me I will get it.

Thanks in advance
