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.

 Eric,
 
 any chance you can try to boot w/o ACPI, boot into safe mode, grab the
 dump (savecore) and send in a backtrace?

 I'm not sure how I can do that when the system doesn't finish booting.  I
 can, however, boot into safe mode without any problems, but when I try doing
 a "savecore" it tells me no dump was found.  Is there something I can
 include in the /etc/rc.conf that will tell it to save that dump anywhere?
 
 Eric

 Can you add DDB to your kernel and get a stack trace from DDB when it panics?
