>Description:
After installing 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, I logged on the console as root and while attempting a shutdown -r now I happened upon the following Fatal Trap 12....

Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 01
fault virtual address	= 0x2c
fault code		= supervisor read, page not present
instruction pointer	= 0x20:0xc08f47e9
stack pointer		= 0x20:0xd5aeda08
frame pointer		= 0x28:0xd5aeda14
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		= 904 (getty)
trap number		= 12
panic: page fault
cpuid = 1
Uptime: 20m21s

The problem also occurs while attempting filesystem activity with a command like..   "find / -name "*.so" .

I will also add that I installed FreeBSD 6.2 Release on the same system and everything worked flawlessly, no kernel panic or trap errors 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, log in as root on the console and run "shutdown -r now".
