Release-6.0
>Description:
When I installed 6.0 the first time I made a mistake and reinstalled it, the second time I put in the cd and booted it up I had this kernel message appear:

Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x3
fault code = supervisor write page not present
instruction pointer = 0x28:0xc0812757
stack pointer = 0x28:0xc1020c84
frame pointer = 0x28:0xc1020cc0
code segement = base 0x0, limit 0xfffff, type 0x1b
= DPL0, pres1, def321, gran1
processor eflags = interrput enabled, resume, IOPL = 0

My box is dual boot XP/FreeBSD 6.0 and sometimes when I'm rebooting, restarting FreeBSD I get this fatal trap and it locks up and I have to reset.


>How-To-Repeat:
Would happen maybe one time in 6 reboots
>Fix:
My motherboard is a Abit NF7-S2 which is nForce2, it seemed to me the support for this chip was not working well.
