cpu2: <ACPI CPU> on acpi0

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc06d01cd
stack pointer = 0x28:0xc1020ad8
frame pointer = 0x28:0xc1020ae4
code segment = base 0x0, limit 0xfffff, type 0x1b

processor eflags = interrupt enabled, resume, IOPL = 0
current process = 0 (swapper)
trap number = 12
panic: page fault
cpuid = 0
Uptime: 1s
Automatic reboot in 15 seconds - press a key on the console to abort
This hardware boots 6.2 and 6.3 just fine. This problem is new with 6.4. I've confirmed the problem with the entire class of machines, this isn't limited to just one system. I tested on 4 different rackable systems dual-intel motherboards and all demonstrate this problem.
I have a test system I'd be happy to ship to someone, or set up for remote console access.
>How-To-Repeat:
Install 6.4RC-2 from CD.
Reboot
>Fix:
Booting from CD works fine.
