unable to execute a uname command as the kernel trap happens before it fully boots
>Description:
After installing FreeBSD 6.3 Release amd64 on a Shuttle XPC SD30G2B, intel 945GC + ICH7 chipset, Intel E6400 core 2 duo 2.13 Ghz, 1066 Mhz FSB processor, then rebooting the following error occurs....

..
SMP: AP CPU #1 Launched! 
Trying to mount root from ufs:/dev/ad4s1a
kernel trap 12 with interrupts diabled

Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 01
fault virtual address	= 0x58
fault code		= supervisor read data, page not present
instruction pointer	= 0x8:0xffffffff804639ba
stack pointer		= 0x10:0xffffffff94c9d4c0
frame pointer		= 0x10:0x0
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 1 (swapper)
trap number		= 12
panic: page fault
cpuid = 1

The system doesn't even finish booting.

I might also add that I installed FreeBSD 6.2 amd64 on this system and everything worked flawlessly, no problems at all.


>How-To-Repeat:
Install FreeBSD 6.3 Release on a Shuttle XPC SD30G2B, intel 945GC + ICH7 chipset, Intel E6400 core 2 duo 2.13 Ghz, 1066 Mhz FSB processor, 512MB DDR2, 667Mhz RAM, reboot.  It won't finish booting.
